"Let joy be unconfined, let there be dancing in the streets, drinking in the saloons, and necking in the parlour."

It is a quote from legendary comedian Groucho Marx. That adage will now ring true for Celtic supporters.

Ange Postecoglou's Celtic team finally won a game away from home in the Scottish Premiership. The first on the road victory for the Australian and the first away success since Valentine's Day. The Celtic faithful can now shout it from the rooftops.

Goals from Kyogo and Jota saw Celtic grind out a narrow 2-1 victory in the Granite City and stave off the fans grumblings and talk of a winter of discontent ... for now.

Ange desperately needed a victory in this one and now, with three points in the bag, it must be a watershed moment for his managerial tenure at the club. The green shoots of recovery need to continue for both the Australian and Celtic and this should be a building block - a platform upon which Celtic can launch their Premiership title challenge.

It should be the traversing of that imaginary corner managers believe their teams have turned after a particularly sticky patch. But will it?

When all is said and done and some perspective is gained Celtic have won just three times in their last nine competitive outings. They still sit sixth in the Scottish Premiership table.

Ironically Ange was left counting the cost of the last international break when star striker Kyogo Furuhashi injured his knee playing for Japan. The 56-year-old will now be cursing his luck at the timing of this two-week hiatus as he's been robbed of the chance to build some much-needed momentum with his side.

Before kick-off in this one, Ange had told his players to use Thursday night's 4-0 Europa League Group G humbling by Bayer Leverkusen as fuel for their fire to produce some sort of reaction against the Reds.

The Aussie made one solitary change to his starting line-up with Israeli Nir Bitton coming into the side at the expense of Tom Rogic. Celtic also had strength in depth on the bench with options to change it up top with both Georgios Giakomakis and Albian Ajeti listed as substitutes.

Was it a hint of a more pragmatic approach from Ange? Was this evidence of Ange deviating from his tactical master plan which he originally said he wouldn't? After all, it was a game that neither side could afford to lose in the 299th league meeting between the two clubs.

There was also an intriguing sub-plot with former skipper Scott Brown featuring for the Reds against Celtic for the first time since he quit the club in the summer. Ironically Brown actually scored the last time he faced Celtic as a player for Hibs back in 2007.

It was talismanic figure Kyogo who proved his class after 11 minutes when he chested home the opener after a sumptuous David Turnbull delivery into the danger area. It was the start that Celtic wanted as they settled into an early rhythm.

Jota then rattled the crossbar for the second week in succession on 39 minutes in a half that was totally dominated by the visitors. Astonishingly, it was the 9th time that Celtic had smacked the crossbar this season.

While Joe Hart palmed a Christian Ramirez fierce volley onto the top of the woodwork, Celtic looked very comfortable.

The mood music changed on 56 minutes when Aberdeen grabbed an equaliser courtesy of Lewis Ferguson header from a corner kick with the visitors Achilles heel in defence being exposed once again from set-pieces. Hart also saved from Scott Brown and Jonny Hayes in a tepid second-half display that was petering out to a draw.

Celtic Way:

Cue twinkle-toed Tom Rogic.

With one pivot, swivel and sublime slide-rule pass, the Aussie had released Adam Montgomery and his accurate low centre was stabbed home by Jota for the winner.

The joy was certainly unconfined for the Celtic supporters who had made the trip to Aberdeen as they went bonkers in the stands.

It could well be the spark that ignites Celtic's season.

Ange remains supremely confident in his ability to turn things around at the club. But he will know better than anyone he'll need to continue to rack up a similar sequence of winning results like today in order to keep within touching distance of league leaders Rangers. The Aussie coach has stressed from day one he knows exactly what the Celtic job entails and understands fully the demands to be successful that has been placed upon him. On that front, he seems absolutely determined to prove he has not been cast in the wrong movie at Celtic.

As he himself noted: “I’m really passionate about this. I want to create an exciting football team and I’m not going to shy away from the fight. It’s all-consuming for me and bizarrely I love this part of it, which people won’t understand. I’m hoping that in six months’ time when they look back, they will know why I have been so resolute and persistent about what we are doing.”

This leads us all back rather nicely to Groucho Marx who once also famously said: "Hello, I must be going...

However, with many more results like the one we witnessed from Celtic today at Pittodrie then one thing will be certain - Ange won't be going anywhere, anytime soon.

For the weekend at least, the manager and his Celtic team finally earned top Marx for their ability to grind out a precious away win.
