Pub Choir. Never too late to join in, they are playing this weekend, which means your singing. OK it may be a bit tricky to get to Australia on time.
So how about this, Couch Choir, same people, you join in, high or low harmony, record it and send it in.

You are doing the 80's Aussie pub rock classic, "Throw Your Arms Around Me" by The Hunters & Collectors. Best sung a little drunk and a little sentimental. Here is a 90's remix version for you to practice with. You have 11 days to go, so get singing.
