After more than three decades since they celebrated their biggest hits, I was intrigued to see what the ravages of time would have done to the famous Sledge sisters.

But from the moment they strode on stage it was obvious we were in for a fabulous boogie night. Their voices were not only instantly recognisable, but also as good as I remembered from the childhood nights spent in front of Top Of The Pops.

As they broke into the classic Lost In Music, the audience was instantly lost to disco fever – proving Thursday nights really are just perfect for red velour and sequins.

With wrinkle-free brows and figure-hugging outfits, their appearance seemed to have stood the test of time equally as well as their music.

And a lack of recognisable hits wasn’t enough to stop them churning out a lengthy set, which they padded with some Stevie Wonder covers and even a dance-off with fans on stage to an extended version of He’s The Greatest Dancer.

Similarly, the finale We Are Family included three or four – or even five – too many choruses.

But it didn’t matter to the audience, probably one of the most eclectic ever to grace Concorde 2 – from trendy students in skinny jeans to 60-year-old housewives drinking vodka. And Patsy Palmer.

Disco may have been a dirty word for many of us for many years, but Sister Sledge showed there’s a small piece of us all that wants to see the glitterball keep turning all night long.
