The reason for all this was an unlikely collaboration between three divas from different eras. Lulu, Chaka Khan and Anastasia, were, by their own admission, not the most obvious sisterhood. But they were, said Lulu, “united in music”. Alas, the music was provided by sequenced backing tracks, but the quality of the singing compensated for that.

The show looked fantastic. Without a band to accommodate, there was lots of room for a two-level stage, stairways, lifts, etc, together with a stunningly effective lighting rig.

The show opened with Chaka’s 1978 hit I’m Every Woman and the crowd were off and dancing. Much as they loved it, the song immediately exposed a flaw in that the three voices struggled to gel in the harmonies. To their credit, at no stage throughout was there any attempt to showboat and the three women seemed to enjoy a genuine rapport. But the highlights were mainly confined to their solo spots. Ain’t Nobody is just a great song and Khan gave it the big treatment it deserved. Anastasia, whose voice was, by some way, the smoothest, most powerful instrument on show, gave us a rather beautiful version of her hit, Left Outside Alone and Lulu, naturally, nailed Shout, with mass Glaswegian backing.They finished with Relight My Fire to mass adulation. Karaoke perhaps, but quality karaoke.
