Only TV connection (apart from appearances as himself in documentaries) I could find for Bob Welch, a onetime member of Fleetwood Mac who would later record one of my favorite albums ever with 'newbies' Buckingham and Nicks (he left Mac before they joined, despite what some media reports say) backing up... there's a slew of 'toobs from that in-concert/on-location show, which only lasted one season...
Zap2it, f'rinstance...
