The best opening act you've ever seen & heard?

"What kind of idiot would boo Linda Ronstadt?"

Probably the ones who came down from Massachusetts. They’re like that.

Billy Squier opening for Queen right after his ’Don’t Say No’ album came out, Hartford Civic Center.

Collective Soul opening for 3 Doors Down, at Mohegan Sun Arena. Left after Collective Soul.

Side note; Went to see Flock of Seagulls on Panama City Beach. Leaning on center stage and high diving the lead singer throughout. Final song, he bent down and asked me if I knew it. I said yes, and he motioned me up on stage to do a duet with him before ushering up the hot girls in the crowd to dance to it. Don't judge me.

That should be 'high fiving'. Stupid autocorrect.

Mental As Anything completely stole the show from U 2 on their American small venue introduction tour at The Rainbow in Denver. Same venue, Fabulous Thunderbirds (original Jimmy Ray line up) were so dominating I can't remember who they opened for

Fleetwood Mac opened for Ozzy Osborn 70 or 71? Bayfront Center St Pete Fla

So many to list, I am very fortunate to have seen so many.  But I thought this was one of the most interesting. 

Elton John opened for Leon Russel.  Anaheim Auditorium, and I believe that was 1971.
