In September 1970, "Know Who You Are" was released as the band's debut single on Polydor. However, it too was a commercial failure, as was its parent album, "Play It Loud", when it was released in November. Afterwards, the band decided to drop their skinhead image and would achieve commercial success with their mid-1971 single "Get Down and Get with It". Speaking to "Classic Rock" in 2005, lead vocalist Noddy Holder recalled: "We got a lot of flak for being a skinhead band, so gradually we changed. We replaced Doc Martens with platform boots. We became more colourful and then it all went berserk – Dave the Superyob with his spacesuits and all the rest. It was a great laugh."
