In January 1976, Wings was actively touring in support of their album "Wings at the Speed of Sound," which had been released in March 1976. This album marked a significant moment in the band’s career as it was their first to feature contributions from all members, showcasing a more collaborative approach. The live recording of "Medicine Jar," performed during the Wings Over America Tour, highlights the band's growing popularity in the U.S. and their ability to captivate audiences with their energetic performances. Interestingly, "Medicine Jar" was written by Paul McCartney's collaborator Denny Laine, reflecting the shared songwriting duties within the group. This tour was pivotal for Wings as it led to their first live album, "Wings Over America," released later in 1976, capturing the essence of their dynamic stage presence during this period of their career.
