yeah that’s the kinda stuff i found everywhere.
there sems to be a lot of guessing and contradictions involved.
the OP began after an off the cuff remark that i made to my son about " something " by the beatles and how i’d read somewhere that it and " yesterday " were way at the top of the cover version list.
there followed the usual arguments. we googled to settle the issue.
round and round we go.
surely the songwriter’s/ musician’s/ and sundry hands-in-the-till people all want their 40cents ( guess ) worth of the songs. therefore, thought i, there must be a list.
or, failing that, a listable database to access.
time for some meta searching.
