When I was gigging for Motown, there were multiple Temptations, Four Tops, Miracles, Marvalettes, and other groups touring the country. The fans didn't know the difference, but that was way before MTV, so we didn't recognize the singers faces.
When I gigged on the cruise ships in the late 1980s, one of the headliners came on with a billing 'formerly with The Patters'. No, he wasn't Tony Williams, the lead singer on the records, but the lead singer in the “Herb Reed Platters”, one of four groups known as “The Platters” touring the country in the 60s and 70s.
Now have the official Lynyrd Skynyrd, Eagles, Kingston Trio, and other ghost bands.
So what's new?
I was going to mention the Platters and the Zombies. Motown.... absolutely. If there's a dollar to be made, someone's going to use the band name and hit the road. And..... practically every beach music band also fits this category. Very few have any of the original members. Some have one degree of separation but others? Who knows? One of my customers was the bass player for one of the big NC based beach music bands, the Embers. I never asked him much about the band but I don't think he was the original bass player.
When you look at the wikipedia member line up on many bands it's like a game of musical chairs switching out and replacing members.
Even ZZ Top is now touring with replacement members. What kind of travesty is THAT?
