A good friend of mine had the Eagles play at his high school prom at Pacific Palisades High School in Los Angeles in 1970 or 1971.
this guy?
no, wait.that was Van Halen...
And they played at the horse show at Santa Barbara in 1972, at the exhibitors party. I went back to the kids at school (I was in elementary school) telling them about this cool band and everyone made fun of me because they were a bunch of unknowns lol!
