William Manchester has been played on 139 lists, including 28 lists in The 2002 Lee Atwater Invitational Dead Pool.
Here's another musician (keyboards) who claims to have played on every single Motown record from the '60s and '70s, and that for all of those sessions, he was paid a total of $80. Aren't there, like, a bunch of these guys now?
