See Who...? saw them too...
I saw so many bands but missed too many I wanted to see... If you only missed one, consider yourself veeeeeerrrrrrry lucky...
I missed Free (but saw early Bad Co), Duane (oh for a time machine), Grand Funk, Foghat, DP2 (the first time), and DP3, Randy Rhoads (when I even had a ticket...! - they have his pic in a beautiful frame prominently displayed in their house - used to look after their alarm system a while back), Montrose (but did see Gamma), the original Spirit lineup (saw later and California numerous times and met a few times), Mountain (with Felix), and it goes on...
Were getting closer to the big five-oh bro... any nerves yet...?
