Pepper's Lonely Hearts Club Band", "Blue Suede Shoes" and "Johnny B. Goode" as adding to Hendrix's more typical concert material.

Both the Reprise and Polydor album liner notes list the tracks in a different order than the actual LPs.

Since the rights to the Royal Albert Hall performances that appear on the original LP are in dispute,[9] the re-release substitutes the recordings of "Little Wing" (3:52) from Winterland on October 12, 1968, and "Voodoo Child" (10:40) from the San Diego Sports Arena on May 24, 1969.
