Obituary: Joni Sledge, the 'We Are Family' disco queen

Joni Sledge, who has died at the age of 60, sang with her siblings in Sister Sledge, the US group whose disco-era smash 'We Are Family' became an anthem for female empowerment.

By the late '70s, the four sisters in the band - Debbie, Joni, Kim and Kathy - were frustrated with only minor success. Kim had started law school. Their record label, Atlantic, then teamed them with the producers and songwriters Nile Rodgers and Bernard Edwards, who as the band Chic embodied the hypnotic rhythms of disco.

The sessions yielded four huge hits that in 1979 brought the group international recognition: He's the Greatest Dancer, Lost in Music, Thinking of You and the title track of their platinum-selling record, We Are Family.

The extrovert Joni Sledge later recalled its recording as a "one-take party".

The band's tight choreography, bright costumes and euphoric style propelled the single to No2 on the US charts as it sold more than a million copies. Its chorus - "We are family, I got all my sisters with me" - might have been merely the literal truth, but it came to be adopted by women as a celebration of their strength and unity.

Sledge was born in Philadelphia on September 13 1956. She was the third of five girls, of whom the eldest, Carol, became a teacher. Their parents were Edwin, a tap dancer who appeared in the original Broadway production of Kiss Me, Kate , and Florez, an actress.

The pair were divorced when the children were young, and it was their mother's example that inspired the girls. Florez held down several waitressing jobs at once and joked later that her daughters learnt to sing because they were locked in the house for much of the day to stop them wandering the streets.

In fact, her mother Viola had been a soprano and she trained the girls. They first performed as "Mrs Williams's Granddaughters" at the Methodist Episcopal church that she ran. They acquired the name Sister Sledge when announced on stage by an MC unsure about what they were called.

Joni excelled at school and later studied for a degree in communications at Philadelphia's Temple University. Nonetheless, by the time Joni was in her mid-teens, Florez had taken the group on the road, acting as manager and tour-bus driver as they played venues on the East Coast.

In 1974 they performed at the concert before the "Rumble in the Jungle" fight, in what was then Zaire, between Muhammad Ali and George Foreman. Gwen Guthrie began to write songs for them and the next year they had their first hit, Mama Never Told Me.

After their major successes, they continued to release albums, and in 1985 had their only UK No1, with Frankie.

Kathy left the group four years later and Joni took on more responsibility. She produced their album African Eyes (1997), which was nominated for a Grammy for best production, and wrote the protest song Brother, Brother Stop after witnessing a shooting.

In 2000, Sister Sledge played at US president Bill Clinton's last Christmas party at the White House.

Five years later they performed at the Glastonbury festival in the UK, and in 2015 footage of them singing We Are Family for Pope Francis went viral when nuns in the audience danced along.

Joni Sledge is survived by a son.
