Happy Birthday is one of the most well known songs of all time. If you’re at a birthday party, you don’t need to be taught how it goes or the lyrics, some one starts and you join in (or not.) You’ve sung this sung since you were a kid. You know the routine. It’s easy.
Wouldn’t it be amazing if your friends all got together and sang your favourite Led Zeppelin song instead? Why don’t we think of doing that? Why don’t we challenge convention?
