An early Radiohead demo is going up for auction this September and is expected to sell for at least $1,500. The then-Johnny Greenwood-less group recorded it as On A Friday in 1986, laying down nine songs—some of which have never been officially released. Tracks on the cassette tape include “Fragile Friend,” “Girl (In The Purple Dress),” “Everybody Knows,” “Mountains (On The Move),” and “Lock The Door.”

According to the auction page, the tape is being sold by someone who went to school with the band.
