Robert Kerr (born 14 February 1940, Kensington, west London, England) is a comic musician who plays trumpet and cornet. He was originally a member of the Bonzo Dog Doo-Dah Band and was persuaded by Geoff Stephens to join The New Vaudeville Band, before forming his own Bob Kerr's Whoopee Band. Kerr was a part of a reunited Bonzo Dog Doo-Dah Band line-up of surviving members, which toured in 2006 and 2008. He and his son, Matt, also operate a t-shirt printing business. Kerr's musical career is described in David Christie's Doo Dah Diaries.
