Here are some of the groups I heard at Jazz Fest. These are not at JF. I found them on YT:
1. John Boutte, not a good quality recording but he is singing the Beatles song "Blackbird."
2. Feufollet, they sang the theme song to Monty Python's Meaning of Life in Cajun French but I couldn't find it on YT

, so here is this song.
3. Lenny Kravitz! Such a good performance and he is 10x hotter than when he first became famous.
4. Trombone Shorty! I saw him playing trombone in a second line when he was maybe 5 years old and now he is closing the Acura Stage!
5. Started off the day in the Kid's Tent because my baby cousin was Irish dancing.
