I'm very impressed by Jack's understanding of what he's listening to. Seems like that was all done in one take too....

What surprises me, and didn't expect, is he's more drawn to the, shall we say more primitive output from earlier years, absent the glossier later stuff.

And he only wants to include the singing where it's really the Supremes on there ["as far as we know" ....as he puts it.] Imagine including such a notion as a requirement !
