"Diamond Hoo Ha Man" is a song by British rock band Supergrass. The single was first played live at Guilfest 2007 in Guildford, England, and this live version was then released as a free download via the band's website (as was its B-side "345"). It is the first official single from the band's sixth album, Diamond Hoo Ha, and was released on 14 January 2008 as a vinyl-only single, limited to 1,500 copies, thus limiting its chances of charting, which it failed to do.
