 The songs remained in the Dead's live rotation throughout their existence.Conspicuously absent from the compilation is "Knockin' on Heaven's Door", a song the Dead performed more than 170 times.Conversely, "It Takes a Lot to Laugh, It Takes a Train to Cry" was performed a few times in the early 1990s, and only once in the 1970s – in the version included here, the Dead are accompanied by Dickey Betts and Butch Trucks, of the Allman Brothers Band.
