[3] After the Second World War ended, Cargill returned to Britain to focus on a stage career, and joined Anthony Hawtrey's company at Buxton, Croydon and later the Embassy Theatre at Swiss Cottage in London.

He became a supporting player in John Counsell's repertory at Windsor alongside Brenda Bruce and Beryl Reid and scored a huge hit in the revue The World's the Limit, which was seen by the Queen and 26 of her guests one evening.

[citation needed] He made his first West End appearance in 1953 in Ian Carmichael's revue High Spirits at the London Hippodrome.

In 1960, Cargill played Gestapo agent Herr Grosnitz in the BBC TV series "The Long Way Home".

These vignette Feydeau farces were originally intended to provide variety for Parisian audiences who were used to more than one production during an evening's entertainment.

[citation needed] Cargill's companion, Vernon Page, recounts that at the time of casting Cargill wanted to sing this duet with Sir Noël Coward and even visited him at the hotel in London where he was staying in an attempt to persuade him to appear, but Coward was either unwilling or unable to agree to the request and he died 15 months later.

This one-off special production by Thames Television also guest-starred Beryl Reid, with whom Cargill sang the duet "I Remember It Well" by Alan Jay Lerner and Frederick Loewe (from Gigi).

[14] In 1986, he starred with Frankie Howerd in A Funny Thing Happened on the Way to the Forum at the Chichester Festival Theatre, in which he played the part of Senex.

(1965) starring The Beatles, The Magic Christian (1969) with Peter Sellers and Ringo Starr and Charlie Chaplin's A Countess from Hong Kong, in which he played the part of the butler, Hudson.

The female voice on the album was not Noel Dyson (Nanny) but that of June Hunt, a friend of Cargill.

He spent his time 'resting' at Spring Cottage, his country retreat situated in Warren Lane, near Cross-in-Hand, East Sussex.

He never made any public acknowledgment of his private life as he felt that to confirm his homosexuality would damage his professional image.

Notwithstanding his reluctance to "come out" in this respect, Cargill was happy in his private life and his wit when not in the spotlight reflected that.

At the time of his death at the age of 77, Cargill was suffering from a brain tumour and was being nursed in a hospice in Richmond on Thames, London.
