One that shocked me was the opener for The Faces on their final tour in 1975.
We learned on the way in that the opener was someone called Peter Frampton. Sounded funny to us in our stoned brains, and walking up the ramps of Pittsburgh’s Civic Arena we kept shouting in funny voices "Peter FRAMPton" and it echoed through the corridors.
So, he came out and basically did a shorter version of what would become Frampton Comes Alive, which came out not long thereafter.
The following summer we went to see him, along with 50,000 other people, headline outdoors at Three Rivers Stadium.
Meanwhile, The Faces show has stuck with me all this time. They were phenomenal even without Ronnie Lane at that time. One of my favorite shows ever.
