I make a distinction between Doo-wop and male vocal groups. I’ll deal with Doo-wop separately.
These vocal groups had a huge impact on the British Beat Groups. I loved their stuff
The Contours
The Drifters
The Coasters
The Platters
The Dominoes
The Midnighters
The Clovers
The Miracles
Isley Brothers
Four Tops
Argyles
Cadillacs
Hollywood Argyles
You nailed it, except for the Temptations. Love the list! Did I miss the Temptations off??? Well spotted.
