Jon, Janine is mixing it up with Gino Washington's "Rat Race" which is also the same backing track as "Like my baby"....
in answer to your question - it's very very common, wouldn't have thought you'd get more than £15 for it. Fathers Angels is of course a bootleg as the only original is on UK MGM. Carstairs has to have "sterling" stamped into the run off and not scratched in - £75 for that.
