The backing of the demo is much closer to that of the "What Four" recording , a kind of 'Munsters' feel to it , the GV track is completely different.
Completely different credits too on the GV label , presumably these are just a fabrication for pseudo-legal purposes ?
Very interesting.
As a side note , there's another version on an EP by the boisterous all-girl garage band "the Rosalyns" in 2014(with the same credits as the demo/What Four) I wonder where they heard the song ?
