I have just been to see the Glen Miller Story on a theatre trip with my WI. Tommy Steele was playing G M.
Now don't get me wrong it was a good show with great music, but I felt Tommy Steele at 79 was just too old to play someone in his 30s or40s. TS's voice was still good but he just looked a bit doddery.
He was on stage nearly the whole show, which showed he had stamina. He danced a bit and had a good stage presence but I felt uncomfortable with him wooing his future wife who looked young enough to be his grand daughter.
I heard Terry Wogan say recently he was looking forward to returning to the BBC after a break. Last time I saw him on a tv programme with a taxi driver visiting local towns I felt he had lost his sparkle.
I don't want to be ageist but I also don't want to see actors/presenters passed their prime still on tv radio trying to recapture how they were.
Having said that I was watching David Attenborough on tv at 88 and he was as good as he has always been, so there are exceptions to the rule.
