On the Up is a British sitcom written by Bob Larbey, about the failure of a millionaire's marriage, and his relationship with his assorted live-in staff.
[1] Tony Carpenter is a self-made millionaire who turned his South London minicab firm into a successful chauffeur-driven car service.
He lives in a large detached mansion in Esher, surrounded by Rolls Royces and BMWs, with a domestic staff who respect him, and whom he adores; Witty and insolent butler/driver Sam (who is also a childhood friend of Tony), acerbic secretary Maggie and cook Mrs Wembley (responsible for the series' catch-phrase of "Just the one", used to respond to the offer of a sherry even if it was her third or fourth).
The open titles are accompanied by the 1st movement of the Handel concerti grossi Op.6 No.11 in A major – a classical instrumental piece, played by the Guildhall String Ensemble.
[3] This continues a pattern from Minder, New Tricks and Stay Lucky, shows in which he also starred and sang the theme tune.
