“Had Enough” is a song written by The Who bassist John Entwistle, and featured on their eighth studio album, Who Are You. It was also released as a double A-sided single with “Who Are You”, making it Entwistle’s second single A-side, after “Postcard” from Odds & Sods in 1974.
Like “905”, “Had Enough” was planned to feature on a rock opera in the process of being written by Entwistle, but was never finished. It was written a long time before work was started on Who Are You. The lyrics describe the main character of the failed rock opera, 905, finally snapping under the pressure and stress of his life.
“Had Enough” saw single release as a double-A side single with “Who Are You” in 1978 prior to the Who Are You album’s release. Despite this, “Had Enough” received far less radio airplay than “Who Are You.” Entwistle later joked that most people probably thought the song was a B-side because it said “Entwistle” on it. It was never performed live by the Who, although it featured in many of Entwistle’s solo concerts.
