In the early days of 92-93, the song frequently featured a "Shortin' Bread" interpolation towards the end of the song.After the summer of 1994, the last verse evolved beyond the mere repetition of "That's my blood down there".
Starting in 1995, a stop-time intro began to occasionally be played during full-band versions. After 1996, every full band performance of this song has included a stop-time intro. In 1999, fans from the original nancies mailing list began organizing to chant "Woo!" during the stop-time intro.
By the summer of 2000, the "Woos" caught on and are now a standard crowd chant at the start of every Warehouse.Dave and Tim versions have continued to contain the original intro, as well as a "Passion" Intro where Dave interpolates the vocal chords from Peter Gabriel's Passion.
Starting in 2003, the jam evolved what has come to be known as the 'salsa jam' outro with a more celebratory 'salsa' vibe.Dave has also interpolated "Louie, Louie" a few rare times during the outro.
Dave frequently played this song to open encores on the 2001 tour. At Dave and Friends shows, Dave and Trey sometimes play this song during their acoustic mini-set during the encore, alternating verses and singing harmony on the refrain. - dmbalmanac
