It was released on the ‘With The Lights Out’ boxset. It features Dale Crover on drums and Dave Grohl on bass with Kurt on guitar/vocals. It was basically Kurt’s idea to go record this song within this session. He titled them as ‘The Retards’ and was on this kick of wanting to start up a lot of bands with friends.
"We went to a practice space that my band shared with The Melvins, we played some of Dale’s songs, some of Dave’s songs, some of my songs, and then Kurt said he had this song Drain You, but it wasn’t going to be a Nirvana song because he couldn’t come up with a drum part, and he just wasn’t sure if he liked it or not. Then he heard Dale’s drum part and everything changed." - Debbi Shane [Engineer.]
Kurt had some of the lyrics in his notebooks and placed a torn-out piece of paper from the lyric sheets and put it in front of him on the floor to read as he did the vocals. The full version of the song (which wasn’t released on the boxset) features an intro saying “We are The Retards, and we are going to play a song for you!”
