Peggy Sue and the Pirates have been whipping up a storm on dates with Kate Nash and are attracting a considerable following despite not being pirates or called Peggy Sue. Brighton-based Rosa "Rex" Slade and Katy Beth "Klaw" Young's stage equipment consists of just two guitars, two stools, a tambourine, melodica and a percussive instrument that looks like a wooden pear. Their music combines a folky sweetness with a punky undercurrent and all sorts of abrasive and rockabilly edges - the missing link between Mary Hopkin, Buddy Holly and Siouxsie and the Banshees. They are Oxfam-glamourous young girls in coloured tights, scarves and spangly outfits, whose audience are virtually their mirror image.

A Peggy Sue and the Pirates gig is not the place to have a dark night of the soul. The girls declare themselves "the best fun you've ever had, prepare to wet your pants". They are subtly sexy and not very subtly spiky, and address unusual subjects. One of their best songs, Superman, tackles the problems of being a superhero, including having to wear the same outfit since 1930. Television, their debut single, is among their weakest songs, which bodes well for their development - although they may need to write more. At two minutes per song, a busy setlist still clocks in at under 25 minutes.

Still, they can hardly be accused of not getting into the Christmas spirit. "Mistletoe available," they yell as they dash off.
