Former Allman Brothers Band guitarist Jack Pearson sat in with Warren Haynes Band at Nashville, TN’s Marathon Music Works on Tuesday night. Pearson emerged during the band’s encore for a run from “Feel Like Breaking Up Somebodies Home” into “Don’t Change Horses” and then back into “Feel Like Breaking Up Somebodies.” He remained onstage as the band closed their show with “Soulshine.” Pearson—a longtime friend of Haynes and member of the ABB from 1997-1999—is the third former member of the Allman Brothers Band to cross paths with Haynes in the past week. Last weekend, Haynes made a surprise appearance at a benefit for onetime Allman Brothers Band guitarist Dan Toler which also featured founding ABB guitarist Dickey Betts. Warren Haynes Band will perform at Geneva, NY’s Smith Opera House tonight.
