Since you asked it as a "couple" question -- definitely Sonny & Cher. \n\nIf you were to ask me to just pick one of these people, it would definitely be Tina Turner!!

Ike or Patton. Although Patton was a little crisp on the sides!

If you're only asking for one, then Elvis takes the crown for vocalist with his emergence in the mid 50's.\nGroup?? Buddy Holly, The Drifters, or Bill Haley & His Comets...take your pick!

LZ, for sure.  Queen had a couple good hits.  LZ stands the test of time.

Normally I would go with anything other than the Bible, but if you saw Blondie's induction into the Rock & Roll Hall Of Fame then you'll know that Debbie Harryis a self centered, washed up, has-been, who should have been a "never-was". She looks more like a used up soccer mom than a punk rock queen. There, I said it.

They are both really good singer/bands, but I would have to choose Shakira.

Just a guess, but I'd say Eric Clapton - for the Yardbirds, Cream, and either Blind Faith or as a solo artist.

Alanis Morissette or Morgan Freeman.

Marlon Brando or Sinatra

Bon Jovi and Eminem...they'd be even cooler though, if they looked like the chick from the Black Eyed Peas!
