From Delilah and What's New Pussycat to Sexbomb and You Can Leave Your Hat On, Sir Tom and his band put on a cracking set of some of his best songs from down the decades.
Jones, 82, had performed seated on a stool and explained that it was because he needed a hip replacement.
Support for the evening came from Australian band Germein.
