Jammin' is a British musical comedy show on BBC Radio 2 that first broadcast on 28 July 2001. It was presented by Rowland Rivron, who also played the drums. In addition to Rowland, there were two regulars in the band, and two guests - usually one comedian and one musician. The two regulars were usually Dave Catlin-Birch and Steve Brown. When Dave Catlin-Birch is on tour, he was usually replaced by Honka James Roby. Brown replaced original regular Richard Vranch in 2003.
