NOTE: It has been reported on several online websites selling movies that Bobby appeared in Please Don't Eat the Daisies, The Sad Sack and Heller in Pink Tights, and that he sang and/or wrote the theme in the film Wait Until Dark. These appearances have never been reported in any book about Bobby and this appears to be false information. Please Don't Eat the Daisies has been viewed by a longtime fan and Bobby DOES NOT appear in this film. Wait Until Dark was rented and viewed by yours truly and Bobby did not sing nor was he credited for writing the theme.
