NOW this was a strange one. Strange but nice I should point out. The wonderful Judy Collins - 80-years-old and still possessing a voice capable of rattling the chandeliers - acting as her own support act and delivering what was at times close to a stand-up routine.

Of course there was plenty of music too and many classic songs from a career that has spanned 60 wonderful years. But what happened to the advertised support? Norwegian folk singer Jonas Fjeld - Judy’s collaborator on her latest album, the excellent Winter Stories, was notable by his absence. The album and indeed Fjeld himself got a couple of honourable mentions in despatches from the stage and two of its numbers, River and Jimmy Webb’s sublime The Highwayman were undoubtedly among the high points of the show.

The concert opened with a couple of vintage tracks, Maid of Constant Sorrow and Chelsea Morning, with Judy on guitar accompanied by her longtime musical director Russell Walden on piano. To be honest she took a little while to get into her musical stride but when she did she was extraordinarily good, punctuating the set list, including classics like Both Sides Now, with anecdotes and some rather whiskery jokes about Keith Richards.

After the interval she was back and wearing a sparkling crimson jacket - an 80th birthday gift from her old friend and fellow sixties survivor Joan Baez. Abandoning the guitar for the piano, she demonstrated a technique that revealed the classical training she received before joining the burgeoning US folk scene of the 1950s. Becoming a folkie was a shrewd move that at the time did little to impress either her mother or her piano tutor but ultimately it brought her into contact with everyone from Bob Dylan and Leonard Cohen to Joni Mitchell and Stephen Stills. And do you know what? I think we’ve all benefitted.

Certainly audiences at The Tivoli have. Although modest in size the venue has become one of Judy Collins’ favourite UK theatres over the years. It’s a privilege to see her perform there.
