The best Les Paul story I heard was he was at a small rock bar in his old age. He asked the band if he could play. They had no clue who the old man was. They made a big fuss about the old guy that wanted to play. The guitar player gave him his guitar. On stage he blew the band away and the guitarist put a microphone in his face saying, "What's your name?" Les said, " It's written on your guitar."
I’ve heard that story.

One time I saw Paul with just a handful of others. There was a quiet couple I noticed because the gal of the pair was a really hot blonde.
At some point Paul mentioned that Jimmy Page was in the house, which was when I recognized him as the other half of the couple. For the rest of the show, Page was loud and obnoxious. I love Page’s music, but he was a dick that night.
