Topsy Turbys' lost song

[Al.Burnett1966]

Along with the killer "Hey Tiger" / "Snake Woman" single, a 5-song sampler was also issued that included 3 more songs, from which 2 were taken for the great Bacchus/Dionysus reissue. The 5th, "Bart's Tunes", which may be an instrumental considering the title, was not picked up.
I've been wondering about this for long. I have a hard time believing anything from the Topsy Turbys wouldn't be at least interesting to hear. Anyone knows?
