Page told "Rolling Stone" in 1975, "We were careful to never release it as a single," which forced buyers to buy the entire album. Despite pressure from Atlantic Records, the band would not authorise the editing of the song for single release, making "Stairway to Heaven" one of the most well-known and popular rock songs never to have been released as a single. It did, however, appear on two promotional discs in the United States, one of them featuring the 7:55 track on each side, and the other as a 7-inch 33 record produced for jukebox operators with "Stairway to Heaven" on one side and both "Black Dog" and "Rock and Roll" on the other. Other "single" appearances were on an Australian EP, and in 1991 as an added bonus with a 20th anniversary promo book.
