BY day, Joanne Slater is a respectable career woman working for a top public relations company.

With her hair neatly tied back and wearing a smart black suit, she politely liaises with some of Britain's business men and women.

At night, however, she becomes punk singer Jo Slaughter -- a girl with bags of attitude, a David Beckham-style mohican, ripped clothes and a studded neck collar.

Joanne began leading her double life in June when she was approached by members of cover band Love BatTery during a punk event held at St Gregory's Social Club, in Farnworth.

Since then the 26-year-old has grown into her alter ego and she has the full support of her mum, June, aged 50, who attends her gigs in a t-shirt emblazoned with the logo, 'punk'.

Joanne, whose brothers Stuart, aged 24, and 16-year-old Chris, also make up her audience, said: "I absolutely love singing and transforming myself from this respectable girl in an office to someone loud and brash on stage.

"We cover a whole range of songs from 1976 to 1979. "It's a really good laugh."

Although she was only a baby when the punk era was in full swing, Joanne, from Tottington, Bury, grew up listening to bands such as The Jam, The Buzzcocks and The Police.

She studied music at Wigan and Leigh College from 1992 to 1993 where she trained to be a singer and learned to write her own material. "Punk songs had a lot of attitude. They were a reflection of youth angst," she said.

It is a far cry from her working life in the Manchester office of national public relations agency Harrison Cowley looking after clients such as the National Lottery. Joanne's next gig takes place at St Gregory's Social Club -- where Bolton comic Peter Kay films his Channel 4 show, Phoenix Nights --on October 26.
