1. The Beatles recorded "Sgt. Pepper on 4-track, not 8-track. A miraculous feat. Of course I knew that, but thanks for keeping me honest, for correcting my brain fart.

2. Only one of Arlo’s kids is in the Guthrie Girls. The other woman is Amy Nelson, daughter of WILLIE! As one reader e-mailed me, if they were on SNL, they’d be household names overnight, they’re just that good.

3. And while I’ve got your attention, I just saw Mary Gauthier. I had no idea. She sang this song about the King of the Hobos that was positively staggering. Without intending to, she left Gaga in the dust. The turn of the phrase, the inflection… Wow!
