- The earliest known live recording of the group, from Dumfries, Scotland on November 16, 1969, has been made available only recently and includes the only documented performances of Buddy Guy’s “Let Me Love You Baby”, Aynsley Dunbar Retaliation’s “Warning” (released on Black Sabbath), Elmore James’ “Early One Morning”, Eddie Boyd’s “Blue Coat Man”, and “A Song for Jim”, the last of which (a holdover from his Jethro Tull days) features Iommi on flute and develops into a drum solo. “NIB”, though finalized musically, sports alternate lyrics.
- The group’s twenty-five minute set from the Santa Monica Civic Auditorium on September 4, 1975, staged exclusively for broadcast on Don Kirshner’s Rock Concert, exists with stellar audio and visual quality.
- Part of the group’s appearance at Cal Jam in 1974 remains available as professionally-shot broadcast footage. The entire show exists as audio on a decent audience recording as well.
