Play good or just play?
In my younger days (gods, that sounds wrong to say even though it's right) I played trumpet and baritone, and could probably pick them up again fairly easily. I also used to play a bit of piano, but that would take me a little longer to get passable at again....
I can 'fake' drums and percussion, even though I never had any formal training in that area.
Last summer at a ren faire I picked up a reed flute (in the alto range) that I practise on from time to time. It came with a fairly simple instruction booklet, that's really not written for someone with my mindset. It doesn't tell me what key it's in so I could get music to play, although I think it's C key, but could most likely be wrong.
