Premise: "Blue Jean" is a song written and recorded by David Bowie for his sixteenth studio album "Tonight". One of only two tracks on the album to be written entirely by Bowie, it was released as a single ahead of the album and charted within the Top 10 in the UK and the United States, peaking at No. 6 and No. 8, respectively. The song is loosely inspired by Eddie Cochran.
Hypothesis: David Bowie entirely wrote at least two songs in his entire musical career.
