Phish spent a week in November 1994 touring with The Rev. Jeff Mosier, who gave the band a crash course in traditional bluegrass playing. They would hone their skills on the bus and in band practice, learning several new tunes along the way, and Mosier would join the band onstage each night for a few numbers. After one such show, on 19 November in Bloomington IN, the band & Mosier gave an impromptu performance outside of their tour bus. Recordings of this have circulated in trading circles since the occasion. Home video footage of the entire crash course was edited into a documentary which circulates in the fan community as well.
