Nigel:

I think my most embarrasing one was Playing the guitar for a large loaded dance floor in the late 70's I was whaling away and singing "That's the way I like it HA HA Ha Ha" broke a little E string, it popped and went around the neck,"twice" keep going, trying to clear the string while still singing, strap came off the butt of the guitar, and I dropped the pick, finished the song and got a standing ovation for the crowd.

That's when I discovered strap locks.....Pose
