Hello everyone
I remember the big "scandal" in music history when it was revealed that most hits from the USA had session musicians, not the musicians who were on the cover. The session musicians were called the Wrecking Crew.
CBC has a story on this documentary about the Wrecking Crew.

A wee bit of music history for you.
Cheers
John
