I recently played at the Monthly Grind which was themed as the "Bob" grind. All the performers played "Bob" songs and everyone was named "Bob" for the night. (Everyone was given a name tag with "Bob" written on it.)
Performers could play any Bob-related songs, i.e. Bob Dylan, Bob Marley, Bob Seeger, Led Zeppelin (because of Robert Plant), etc. I didn't feel like going with anyone other than the obvious, Bob Dylan, so I played two of his songs. I was the last act! That surprised me. I was very nervous, too. Here are the videos!
