On March 26, 1972, David Crosby and Graham Nash, always ready to lend a hand to help a worthy cause, headlined the This Sheriff's Benefit Concert to help raise awareness of prisoner issues. The show also featured local groups Earth Rise and Stoneground, as well as Elvin Bishop. Crosby & Nash had just finished recording their self titled debut album, which included such songs as Southbound Train, And So It Goes and Immigration Man. Nash has also recently recorded a solo disc, Songs For Beginners, which featured such classic tunes as Military Madness and Chicago. Three songs into the show, Neil Young joined Crosby and Nash, a wonderful surprise as the 3 had not performed together since CSNY finished touring in 1970. It would be another 2 years before the foursome would reunite for a memorable, but turbulent, tour in 1974. In the interim, fans had to be thankful for unannounced reunions such as this one.
