"Queen wanted to release Bohemian Rhapsody as a single, but were told it was too long and would never be a hit. They gave a copy to Radio DJ Kenny Everett- if he promised not to play it. Everett proceeded to play the song in full 14 times in 2 days, and hordes of fans attempted to buy the single. When the band wanted to release the single in 1975, various executives suggested to them that, at 5 minutes and 55 seconds, it was too long and would never be a hit. The song was played to other musicians who commented the band had no hope of it ever being played on radio. According to producer Roy Thomas Baker, he and the band bypassed this corporate decision by playing the song for Capital Radio DJ Kenny Everett: "we had a reel-to-reel copy but we told him he could only have it if he promised not to play it. 'I won't play it,' he said, winking ..." Their plan worked—Everett teased his listeners by playing only parts of the song. Audience demand intensified when Everett played the full song on his show 14 times in two days. Hordes of fans attempted to buy the single the following Monday, only to be told by record stores that it had not yet been released. The same weekend, Paul Drew, who ran the RKO General stations in the States, heard the track on Everett's show in London. Drew managed to get a copy of the tape and started to play it in the States, which forced the hand of Queen's US label, Elektra. In an interview with Sound on Sound, Baker reflects that "it was a strange situation where radio on both sides of the Atlantic was breaking a record that the record companies said would never get airplay!" Eventually the unedited single was released, with "I'm in Love with My Car" as the B-side. Following Everett's escapade in October 1975, Eric Hall, a record plugger, gave a copy to David "Diddy" Hamilton to play on his weekday Radio One show. Hall stated "Monster, Monster! This could be a hit!"" Source:https://en.wikipedia.org/wiki/Bohemian_Rhapsody?wprov=sfla1
