<P> Carry On Screaming was the second film in the series to have a sung main title theme - and the last until Carry On Emmanuelle in 1978 . The theme song "Carry On Screaming" (film version only) was credited as "Anon" and was thought to have been sung by Jim Dale who appears in the film . The singer is actually Ray Pilgrim, a session singer who sang for the Embassy label . A vinyl 45 rpm version of the song was also released in 1966 (Columbia DB 7972) by vocalist Boz Burrell, before he became bassist for the bands King Crimson and Bad Company . </P> <P> Charles Hawtrey was added to the cast at the eleventh hour, after American distributors specifically requested him, as he was such a hit and crowd - pleaser with audiences there . He replaced Sydney Bromley in the role of Dan Dann . </P> <Ul> <Li> Harry H.
