An improvisational musical excursion by Midwest rock band Umphrey's McGee (the best live band around these days). A "Jimmy Stewart" involves sections of music built upon by each band member, by using hand signals and on-stage communication. This kind of improvisation rarely ever falls flat, and will always keep the listener (or observer) interested. Visit umphreys.com for free podcasts.
Very similar to the Rick James. If a guy is really pissing you off, load your hand with Ranch salad dressing and go up to him...slap him in the face...and say "I'm Jimmy, Bitch"
