Something to Ponder

What if the world had not lost some of the great musical artists at such a young age.  What kind of music would Bob Marley be putting out right now?  Would reggae be even more popular, would Bob Marley ever been as popular as he is now?
How many times would Jimi Hendrix changed they way we think of guitar playing?  Would we have fallen in love with Stevie Ray Vaughn, would Jimi be busting out the Star Spangled Banner after 911?
Would Led Zeppelin still rock?  Would Plant be playing bitch music with Allison Kraus?  Would they be washed up but still cool like the Stones, or would they still rock hard?
What about Elvis, would he beat out Jack Nicholson as the coolest old dude alive?  Would he still be bustin moves in his late 70's?  Would we have had those bad Elvis remix songs?
How about Guns and Roses, what if Axel would have died, would they have gone down as a top 5 band of all time instead of a wacky Days of Our Lives episode?  Just some thoughts for a weekend pondering.
