highlighted the guitarist's voice instead of Kiedis'. The original, longer version of this song is featured on the bonus Mother's Milk CD, which contains additional verses and an extended bridge. In this version, Kiedis' vocals are mixed to appear more prominent. In 1988, former guitarist Hillel Slovak died of a heroin overdose. The song serves as a tribute to Slovak; according to Kiedis, "It was a song that described what it was like to be a drug addict, to have that ego and to think you were impenetrable and impervious to the forces of nature and life. But it was also a love song for Hillel." The guitar riff of the song "Knock Me Down" was based on the song "Miss You" by The Rolling Stones. "Knock Me Down" is a playable track on Guitar Hero: On Tour. Live performances "Knock Me Down" was performed often during the Mother's Milk tour but has not been performed since 1990. Group photographer Tony Woolliscroft once requested it at a private studio rehearsal many years later; Frusciante launched into the opening chords, but Kiedis refused to sing it.
