Saw the Outlaws in San Diego, back in the early '70s, before they demolished the old Balboa stadium that had been built in, well, here, I'll let wikipedia tell the tale:
The original stadium was built in 1914 as part of the 1915
Panama–California Exposition with a capacity of 15,000. The stadium expanded in the 1960s to a capacity of 34,000. Due to
seismic safety concerns, it was demolished in the 1970s and a smaller venue with a 3,000-seat capacity was built, opening in 1978. Most of the original stadium's distinguishing architectural features were removed.
If you look at a picture from before, and one from modern times, the older one looks like what you'd expect from a big name venue. The new one looks like a typical high school or small college stadium, which it is, since San Diego High School is the primary user of the stadium.
Anyway, the Outlaws, the Doobie Brothers, and the reformed Allman Brothers. The concert is pretty hazy in my memory, so I figure I had a good time.
