Your first concert was to see who and when?

Right after I returned stateside from Vietnam, August 1971, Alexandria, LA, Rare Earth. 

Cream Chastain Park ATL 10/27/68.  I was 16 and it was life changing.  Been playing guitar ever since.

March 28, 1986. Rush Power Windows Tour, Joe Louis Arena in Detroit. Marillion was the opening act. It was a fantastic show!

Vanilla Fudge in I think 1967. I was in middle school. They were/are fantastic!

Wow some amazing concerts here!

Mine was during a family visit to Phoenix in 1970.  The headliner was Three Dog Night, but the opener was Blues Image, still one of my favorite bands.

The following year, we visited Phoenix again and were eager to see another concert.  Opened the paper and found the ad, Three Dog Night again!  This time the opening act was little-known band, the Doobie Brothers.

Two great concerts!
