I started on recorder at primary school, then a bit of classical guitar in top juniors (don't know what 'year' that equates to in today's money), then got really into keyboards, which I still play from time to time, but I had a revelation when I heard Rush - "that fella with the nose plays keys AND bass? ". Also my brother and I were dabbling in songwriting at the time and he's a much, much better guitarist than me, so we just needed a bass player. Long story short I bought a bass and ditched the keys (as my main instrument).
secretly I wanted to be able to move around the stage a bit like a guitarist, so the days of playing keys were numbered...
