Colbinabbin Hotel manager Julie Price, who organises the weekly choir sessions, explained how the unique project began.
“A couple of years ago, we had the thought of recording Christmas songs on our phones,” she said.
“Then someone made up QR codes for them that we could stick on the barrel, the candles and then if people wanted to, they could just walk along and put their phone up, scan the QR code.”
The choir uses repurposed barrels as candle decorations are placed throughout Colbinabbin's streets.
“We have these barrels that have been made into candles, and we put them on the street in Colbinabbin,” Ms Price said.
“You can go up to the barrel and if you are going for a little Christmas, or Christmas Eve stroll or any time in December, you can listen to the pub choir singing Christmas carols.
“We also have some big metal Christmas trees, with cutouts for you to put your face into and have your photo taken with the silos in the background.”
The barrels, which previously contained stewed apples, are much lighter than traditional 44-gallon drums, which Ms Price gets the local football club to put out.
The pub choir meets every Tuesday night at five o'clock for an hour at the hotel.
“I play the guitar and we have a collection of songs. I have a big box of printed words that we rotate through,” Ms Price said.
Beyond Christmas carols, the choir tackles diverse musical themes throughout the year, including Father's Day songs and a Bob Dylan tribute in May.
“In November, we are doing a Neil Young tribute because he is 80 years old,” Ms Price said.
The informal sessions are open to anyone, with no fees or sign-ups, though participants purchase their own drinks.
Everyone is invited to wander through Colbinabbin from early December, listen to the Christmas carols, and take their own Christmas selfie in front of the silo art, as well as enjoy a meal at the pub.
