Also appearing on "Mind Games" are songs that indulged Lennon's affinity for pure rock 'n' roll, such as "Tight A$", the title of which was a pun on the expressions "tight as" and "tight ass". The track is in the rockabilly style with a 1950s sound, along the lines of songs that inspired Lennon in his youth. Another rock track, "Meat City" contains lyrics more in keeping with Lennon's earlier penchant for obscure imagery over the personal. The song was a boogie piece until late in 1971, when it began to take its final form, although with improvised lyrics. By late 1972, Lennon had rewritten the words and finished developing the melody.
