Brenna Whitaker playing a show and notices John Mayer in the crowd. After a bit of charming John gets a guitar in his hand and the rest is history. The whole jam is worth a listen, every instrument and voice gets to shine. I think this is a beautiful example of people being able to jam together without previous practices. Would of course love to see you break down the chord prog, and a few johnny boy licks. Thanks for reading. THANKS!
