Since Hendrix was obligated to supply an album of new material, the set lists for the Fillmore East shows contained mostly new songs. Although songs such as "Lover Man", "
Hear My Train A Comin'", and "
Bleeding Heart" had often been played by the
Jimi Hendrix Experience, they had not been issued on record. At Woodstock, Hendrix performed early versions of "Message to Love", "Izabella", and part of "
Stepping Stone", which were not released officially until the 1990s (although studio versions of the last two were released as a single in the U.S. in April 1970). In addition to these tunes, several new Hendrix compositions were debuted and recorded: "Power of Soul", "
Machine Gun", "
Ezy Ryder", "Earth Blues", "Burning Desire", and "Who Knows". Miles also supplied a couple of originals: "Changes" and the jam number "We Gotta Live Together". The set lists included the
Jerry Ragovoy and
Mort Shuman composition "Stop" (a hit in 1968 for
R&B singer
Howard Tate) sung by Miles. The popular Experience numbers "
Stone Free", "
Foxey Lady", "
Voodoo Child (Slight Return)", and "
Purple Haze" were sometimes played for encores. Experience Hendrix indicates that
Songs For Groovy Children "boasts over two dozen tracks that have either never before been released commercially or have been newly pressed and newly remixed". Tracks not previously officially released in one form or another, include "Ezy Ryder", "Changes", "Message to Love", and "Stop" from the December 31 second show; and "Lover Man", "Steal Away", "Hey Joe", and "Purple Haze" from the January 1 second show. Additionally, longer versions of previously released tracks include "Who Knows" and "Stone Free" from December 31, 1969 second show; "Who Knows" and "Stop" from January 1, 1970 first show; and "Power of Soul", "Changes", "Machine Gun", and "We Gotta Live Together" from January 1, 1970 second show. However,
AllMusic critic Sean Westergaard notes that "We Gotta Live Together" lasts "just under ten minutes", while the full performance lasted 18 minutes. ==Critical reception==
