I always have trouble with the song, The Wanderer when I'm playing drums. The beat I play is a 4/4 shuffle, but the background vocals that go Wah, Wah Wah fall on the offbeat. So when I sing and play at the same time, I really have to concentrate or I screw one or the other up. Otherwiese I have perfect timing and Rythem. Go Figure?

I was taught to sit at the Piano and improvise whilst I sing and/or Scat over the soloing. This helps ryhthm, timing, and improv skills.
