Wrong time in life - I wasn't interested then. I wish I had been, but I wasn't. Brief history:
Primary school - sang (until my voice went weird and couldn't do all those solos they used to want me to do) and played recorder. I know they were trying to get us to sight read but I always memorised. That was fine until one time I couldn't figure out the song, so when it came time to play it I stuck my hand up and asked to go to the loo, then took my sweet time about it. Quit recorder group because the second last boy quit and left me as the only boy. Girls were ikky then, so I quit too. Was offered the chance to play cello but I couldn't be arsed with the huge thing.
Secondary school - compulsory music for the first two years, wasn't interested, just saw it as a skive period and used it to skive.
Didn't take up the bass until my 30s, joined my first band in 2009 at the ripe old age of 34. I grew up late, what can I say? It wasn't school's fault, it's not as if I wasn't presented with opportunities, I just didn't want to take them up then. So I guess I didn't let school help me with my musical life, looking back I marvel at how stupid, wasteful and downright ungrateful I was back then. Oh well, live and (maybe) learn!
