On Saturday night at Summer Camp Umphrey’s McGee offered an instrumental tribute to the late Gregg Allman. During the transition between “Cut Off” and “Hangover” the group shared a portion of the Allman Brothers Band’s “Jessica.” While not written by Gregg Allman, the song was an ABB staple for many years. It appears on the group’s 1973 _ Brothers and Sisters_ record, which also contains Allman originals “Wasted Words” and “Come and Go Blues.” Although Chuck Leavell performed the piano on the original version (with Gregg on organ), over the years to follow Allman very much made the song his own, as one can see on the video below.
