It would be easy to assume that Tony Christie has Peter Kay to thank for his Lazarus-like career resurrection.
In fact it was another Northerner who tapped into the coolness of Christie.
Jarvis Cocker wrote Walk like a Panther for him six years ago and he found himself back on Top of the Pops after an absence of a quarter of a century.
Then Kay picked Is this the Way to Amarillo as his personal signature song and it introduced him to a new generation of fans young enough to be Tony's own grandchildren, who were in the audience at Symphony Hall.
Like many children of the '70s, Kay probably grew up with Christie bubbling away at the back of his consciousness. Another of his hits, Avenues and Alleyways, was the theme tune to suave 'tec show The Protectors and Christie chose this as the first in his set at Symphony Hall.
Dressed in shiny tux and crisp white shirt, swept back hair just touched with grey at the temples, he looked like the Vegas headliner he would have been had he been American.
A showman in the Tom Jones mould - though rather less solid as he moves across the stage - the slightly psychedelic light show behind him is a nod to his musical heyday.
He blended his own hits with those of other crooners he admired, including his own tribute to the Rat Pack. Though his voices lacks the malty mellowness of Sinatra he perfectly captured Sammy Davis.
A mini version of West Side Story showed that his style of delivery does not suit all musical styles, however, he was redeemed by an exhilarating rendition of MacArthur Park.
Is this the way to Amarillo was delivered with humorous aplomb, and plenty of eager audience anticipation, before ending with another Neil Sedaka composition, Solitare.
