An interesting life Glen Campbell has had, and still at it, he was here in Invercargill last month (that's the bottom of the world folks).
As part of the session band Wrecking Crew as told here ...

There were probally many other excellent drummers played on his tracks and toured, perhaps album covers will reveal who they were?
