YOU may have bought a seat to watch The Osmonds last night but there was no chance of sitting on it: the audience rose to its feet with the Safety Curtain.
From then on it was a sea of waving hands, cheering, singing along and some screams.
It was just as well the group - four of them - managed to stage a show which matched the adulation.
Wayne and Merrill may have grey hair and Jay and Jimmy are now middle-aged but The Osmonds have not lost the gift of showmanship. Even without the star turns of Donny and Marie, The Osmonds manage to stage a pretty good concert.
The mainly female and middle-aged audience loved every gesture, every song and every move.
Dressed in long Wyatt Earp jackets - and Jimmy wearing a striped tie with a purple shirt! - The Osmonds looked good and sounded good.
They delivered most of the big hit numbers like Love Me For a Reason and I'm Gonna Knock on Your Door with broad grins and breathless energy, apparently enjoying the night as much as their scarf-waving, mobile photo-taking fans.
"What's it feel like being a teenager again?" asked Jimmy, 48.
Each had a solo spot including Jay, 50, doing a tremendous drum solo on his number, Wayne, 54, playing wild guitar and Merrill, 52, with his distinguished beard, just enjoying singing.
Jimmy - naturally - gave us his rendition of Long Haired Lover From Liverpool during which some giant balls were lobbed off the stage to be thrown around the audience.
