• When it comes to "rock" songs, Queen is best known for "We Will Rock You," but three yeas later they released this lesser-known tribute to the pleasures of rock and roll. It's fairly straightforward, inviting a girl to come along for a rockin' ride.
• Queen drummer Roger Taylor wrote this and wanted to sing it, but Brian May and the producer Reinhold Mack suggested Freddie Mercury should. They eventually recorded both versions, Brian voted for Freddie's, John Deacon voted for Roger's. Finally they decided to make a compromise and leave Freddie singing the intro and Roger taking the lead vocals from then on. Mercury sang it on stage.
• Synthesizers were played by the producer Reinhold Mack. Freddie Mercury played organ in the song. >>>

• The line, "I said Mama, I ain't crazy" is likely a reference to the 1972 Slade hit "Mama Weer All Crazee Now."
