The guy was Barry Charnley who rep'd for CPMG back then – KenR did the vocals with his Toledo group.
I really liked the package sung with a Dallas group, especially the cut that went, “It's time for Radio Dave” – something about the harmonies, I guess.
If you get a chance to hear the “Around Alfasound” presentation, you can hear the ERI jingles in session.
