"'Betcha By Golly Wow' (but I don't think it was The Stylistics.)"
Probably Aaron Neville. They run his version all the time.
"Been hearing a strange (and terrible) version of 'I Want You Back' lately. It is not the original by the Jackson 5."
I have no idea who this is. It's some teenybopper girl whose shrill, grating voice and insipid, overly-melismatic style I really hope change soon. Much as I hate the things, she really sounds like she could use a few cigarettes every now and again!
"I would definitely say a Caribbean-sounding version of 'I Got You, Babe' is appropriate even for today's AC radio."
I'm fairly sure that's Big Mountain with that lead-singer girl from the Pretenders (can't remember her nameright off the top of my head, but she was the one who once commented on how "Muzak filled the air from Seneca to Cuyahoga Falls".) Don't quote me on that, though.
"More classic adds on FM1 recently: 'Love Train' 1973, 'Midnight Train to Georgia' 1973, 'Nobody Does it Better' 1977 and 'Clocks' 2003."
Again, all of which have been in regular rotation on FM1 for years. Also, I would hardly consider anything from 2003 to be remotely "classic" yet. Might want to give it another 11 years! ;o)
