I'm very surprised that amongst all the contributions on this thread that acknowledge Marty Feldman as the wordsmith for many of Ramblin Sid's songs, no one has further praised Marty for other musical efforts.I have a tape from about 1970 ish of an album of songs sung by Marty. All are spoofs of various styles including folk and included are such classics as a list of the ingredients of HP sauce sung in fake french, the 'five to eleven waltz', 'Is it wrong to love an elephant?' (I still sing this occasionally!!)etc etc etc.
He had a real genius and from the feel of the pastoral songs on this album, I would guess that it was Marty that had the knowledge of, and feel for, traditional music in the Ramblin Sid team. Kenneth was wonderful as well, but Marty was a real one off.
