Mean Mr. Mustard

"Mean Mr. Mustard" is a song written by John Lennon (credited to Lennon/McCartney) and performed by The Beatles on their album, Abbey Road.

Inspiration
Written in India, John said that the song was inspired by a newspaper story about a miser who concealed his cash wherever he could in order to prevent people from forcing him to spend it. He obviously didn't think highly of the composition, as he described it in Anthology as "a bit of crap I wrote in India."

A demo version of the song was recorded in May 1968 at Kinfauns, George Harrison's home in Esher, and appears on Anthology 3. In that version, Mustard's sister is named Shirley. Lennon changed it to Pam when he saw the opportunity to ease the segue into the song "Polythene Pam", which follows "Mean Mr. Mustard" on the album. According to Lennon, "In 'Mean Mr. Mustard', I said 'his sister Pam'—originally it was 'his sister Shirley' in the lyric. I changed it to Pam to make it sound like it had something to do with it." Additionally, the original version of the song was a quieter acoustic rendition.

The Abbey Road version was recorded with "Sun King" in one continuous piece.

Sgt. Pepper's Lonely Hearts Club Band Version
The version in the Sgt. Pepper's Lonely Hearts Club Band (movie)film was performed by Mean Mr. Mustard (played by Frankie Howerd) and his evil robot companions named the Computerettes. As with the performance of "She's Leaving Home" also in the film, the computerized singing of the Computerettes was performed by the Bee Gees. It is reported that Steven Tyler also performed in this version.
