"Lazy" is a song by Deep Purple from their 1972 album Machine Head. A live performance of the song can be found on the album Made in Japan, released later the same year. The song starts out as an instrumental, keyboardist Jon Lord plays an overdriven Hammond organ intro, followed by the main riff and with the solo swapping between him and guitarist Ritchie Blackmore. Vocalist Ian Gillan comes in with the vocals later in the song. He also uses harmonica both on the studio version and live. At over 7 minutes long, it is the longest track on the album, and live versions were often extended past 10 minutes.
