I'm with you on these choices!
I saw Jackson Brown a few weeks ago. He opened for Tom Petty and outperformed him IMHO. I was so stoked because he did a song off of "I'm Alive" called "Everywhere I Go"
Santana! You know where I'll be when you're in Vegas.
I've seen Santana more times than any other artist, and still counting. It's just great fun. Carlos was my first concert, at the age of 10. He played with Tower of Power in Vegas, at the Aladdin. I still have the concert stub.
Anybody into Moody Blues or Rare Earth?
How about a really obscure Dave Loggins?
