In 1933, Ambrose was asked to accept a cut in pay at the May Fair; refusing, he went back to the Embassy Club, and after three years there (and a national tour), he rejected American offers and returned to the May Fair in 1936. There were over 700 guests, including
Winston Churchill and
Anthony Eden, the house and gardens were lit up and visible for miles, and the band played in a pavilion as the guests danced on the vast lawn into the early morning. It was by far the highlight of the
social season, and in hindsight has been styled by some as "the last season ever". Socialite
Henry (Chips) Channon noted in his diary: “I have seen much, travelled far and am accustomed to splendour, but there has never been anything like tonight”. His major discovery in the years leading up to the war was the singer
Vera Lynn, who sang with his band from 1937 to 1940 and, during the war, became known as the "Forces' Sweetheart". Lynn married
Harry Lewis, a clarinettist in the band, in 1939. Other singers with the Ambrose band included
Sam Browne,
Elsie Carlisle,
Denny Dennis, who recorded a number of duets with Vera Lynn,
Max Bacon (also the band's drummer),
Evelyn Dall and
Anne Shelton, with whom "When That Man is Dead and Gone", a jibe at
Adolf Hitler, written by
Irving Berlin, was recorded in 1941. Ambrose's signature tune was "When Day is Done". After a short period back at the May Fair Hotel, Ambrose retired from performing in 1940, although he and his orchestra continued to make records for Decca until 1947. Several members of his band became part of the
Royal Air Force band,
the Squadronaires, during the war. Ambrose's retirement was not permanent, however, and he formed and toured with the Ambrose Octet, dabbling in management. His final widespread tour of Britain took place from May to September 1956. From then on he remained active in management, with his artistes including
Kathy Kirby. ==1950s and 1960s==
