In no order whatsoever:
1. John Fogerty -Between the upbeat, folky nature of his music and his voice, Fogerty is a giveaway.
2. Brad Delp (Boston, Deceased this year

) - Brad Delp could go to such high registers that only Rob Halford could have approached.
3. Yusuf Islam / Cat Stevens - There's a soothing quality to his voice in his new (2006) album. It's far different from anything else I've heard. His voice is really smooth.
4. Fred Schneider (B-52's) - Him and Kate Pierson are easily recognized.
5. Ronnie Van Zant (Lynyrd Skynyrd, deceased) - His southern drawl makes original recordings sound different than his brother Johnny, who fronts the band now.
6. Jerry Reed - There's not much difference in vocal tone between his early recordings and his later stuff. When you hot, YOU HOT!
7. Rob Halford (Judas Priest, Halford) - Some of the notes Rob Halford hits in his upper register are earsplitting.
8. Janis Joplin
9. Dusty Hill (Bassist of ZZ Top) - Billy and Frank will say that their favorite songs to play are the ones that Dusty sings. Everyone loves Tush. I saw ZZ Top september 15th in Kansas City. Dusty didn't seem to go as high as he did in the recordings, but it was a great show nonetheless.
10. Ozzy Osbourne - wellahyacantreallyhehebuhubagbabaggadasthayoureabunchofbloodymagicians. Bark at the Moon! I saw him October 29th here in Fargo. If anyone has been experienced to rock and roll, and cant tell by the singer who Ozzy Osbourne is, they have failed. He puts on one hell of an act at 59. I'm glad I got to see him.
