“I Just Don’t Understand” is a song released by Swedish born singer and American citizen Ann-Margret. It charted at No. 17 on the US Billboard Hot 100 chart in 1961. It was one of the first records to feature a fuzz-tone guitar. It was later recorded by The Beatles on 16 July 1963 at the BBC Paris Studio, London for the Pop Go The Beatles radio show and appeared on their 1994 compilation album Live at the BBC, with lead vocals by John Lennon.
In 1965, Australian pop star Normie Rowe presented a rockier version. This proved popular in its own right and appeared on the B-side of his Australian top 10 hit, “I (Who Have Nothing)”.
American indie rock band Spoon included a cover of the song on their 2014 album They Want My Soul.
