I play the guitar (bass, electric and acoustic), the saxaphone, the keyboard and the Irish whistle. Have been doing for years. I'm currently in a band of five people (they are all friends whome I used to go to school with years ago) - we play in the local pub about twice a year. When we do play, we do a lot of video game themes, but vary the way we play them a lot. We also like to do covers, as none of us can write very good songs :D
We tried to write one once, and it failed miserably, so we played the Tetris theme straight after.
