"Maybe I'm a Leo" is a song by the English rock group Deep Purple, from their 1972 album Machine Head.
History
Roger Glover says: "I wrote the riff to "Maybe I'm a Leo" after hearing John Lennon's "How Do You Sleep?". I liked the idea that the riff didn't start on the down beat, like 99% of riffs do. Most of the songs on Machine Head were from the first take, or not long after."[1]
Singer Ian Gillan is a Leo (born 19 August), the only group member at the time with that astrological sign.
