The Deep Purple concert that took place within a couple months of that one was even better. Sammy Hagar was supposed to open but hurt his knee, so the got a band named Girlschool to open. Everybody sat outside smoking until they were done.
I remember the song Baker Street coming on Y-100 or WSHE or Zeta 4 back in 78 when I was a kid and was sick for a few days reading a couple of books. Just hearing that song brings me right back to that exact time and place.
