Michael had just released his first solo album, The Garden of Love Light, which features Jeff Beck and Carlos Santana. Tommy's band took the track 'Delightful' and played a beautiful version of it here, catching the groove just right. There's a later show on the CD this was taken from (First Time Live) which is much quicker, and loses the groove as a result.
So here we have just about the best example of Tommy Bolin's short-lived band. And it's obviously captivated folks, to judge from the comments on the YT page. Coming up for 55,000 views at the time of writing. Enjoy.
