Good list so far
I would addFrank Sinatra
Keith Whitley
Liberace

@ginx:
lol, I was thinking of Frank and also Dean Martin...but I thought to myself.."Oh, they won't know who that is".

@MooMawI love love love Dean Martin!

Wasn't this done a few years ago with Celine Dion doing, "If I can Dream", with Elvis...it was also done by Martina Mcbride with Elvis, doing "Blue Christmas". Pretty Cool technology and neat with duets....but is still just a video.

John lennon
Janis Joplin
John bonham

oh Yes...Janis...thank you.

@MooMaw: Me and Bobby Mcgee

@Fairlane67: Elvis is currently on "tour" in Europe via advanced video technology with a younger back-up band. For years they did this with the original band and orchestra but needless to say it became physically demanding for people their age. Also some of them have since passed away.

Bradley Nowell

WHO?ok, I looked him up...from a band called Slime?

@mm4731: Ooohh, that's a good one! Santeria and Wrong Way are my favs!Wasn't he in his 20s when he died? RIP*edited to add...and I'm not even a pot smoker from Cali.

@MooMaw: Sublime.
