Because of the size of the cassette package, Warner Bros. sold the cassette version of The Rutles album without the booklet. Instead, a card (left) was included instructing buyers to write to Warner Bros. for a free copy of the booklet, to be received by mail. Presumably, this wasn't appealing enough to justify a sticker on the front of the cassette box reading "Free Cassette With The Purchase Of This Promissary Card."

Also, mysteriously, the cassette version has the sides reversed from those on the LP, with Side 1 containing the Rutles' final songs, and Side 2 presenting the earlier Rutles works.
