Felix Mendelssohn's Hawaiian Serenaders

Mendelssohn began to have health issues, but the Serenaders could perform without him. By October 1950, he had quit touring altogether, but continued with the broadcasts. Then, in December, he underwent an operation for "glandular problems" and was back on the road by May 1951. Unfortunately, his health became worse, and on 4 February 1952, after entering Charing Cross Hospital, he died from Hodgkin's lymphoma at the age of 40. He is buried at Golders Green Jewish Cemetery.

During World War II, Mendelssohn spent some time in the Life Guards, but still managed to regularly broadcast with his Serenaders on Songs of the Islands, and later on Hawaii Calling featuring singer Rita Williams. After the war, the Serenaders appeared on radio shows like Workers Playtime, Variety Bandbox, and Music for the Housewife, as well as many variety tours. The group also appeared in two films: Demobbed (1946), starring comic Nat Jackley and the "Sweethearts in Song" Anne Ziegler and Webster Booth; and in 1951, Penny Points to Paradise, starring Harry Secombe, Peter Sellers and Spike Milligan (The Goons trio).

In 1946, the band suffered financial problems, which culminated in 1950 when Mendelssohn appeared in a bankruptcy court. He put together a tour to The Netherlands to repay his debts, but it was a financial disaster, as the expenses were more than the payment received, and this left the whole company stranded without the fare back to England. Mendelssohn negotiated with a local British Army camp, offering free shows to the servicemen in exchange for overnight accommodation and subsidised transport back home.

His first recording for Parlophone was in November 1939. Mendelssohn then got a two-year contract with its parent Columbia Graphophone Company in 1941.

Realizing a long-standing ambition to form a Hawaiian band, in 1938 Mendelssohn took over a band led by Canadian steel guitarist Roland Peachy and renamed it "Felix Mendelssohn's Hawaiian Serenaders". While dressed in a white suit and always wearing a Polynesian garland of flowers around his neck, he merely stood by while the talent performed. In 1942, the Serenaders appeared in a variety show called The Yankee Clipper. This included a troupe of Hula Dancers from around the world, which he called his "South Sea Lovelies", for which he would make up a story about each dancer, involving audience members in the show. At its peak, the troupe numbered about fifty people.

Felix Mendelssohn's Hawaiian Serenaders was a popular Hawaiian music band started by British frontman Bartholdy Felix Mendelssohn (19 September 1911 – 4 February 1952). They are best known for making Hawaiian music popular in England and throughout Europe during the late 1930s and throughout the 1940s. The group were based in London.

Mendelssohn was born in Brondesbury Park, London, into a theatrical and entertainment family. He was the son of a stockbroker, Martin Mendelssohn (1877 – 1957) and Kate Lazarsfeld Warner (1889 – 1944) whose father was Dick Warner, the head of Warners International Theatrical Agency. Dick Warner changed the culture of popular entertainment, moving away from singing saloons and contracting more classical performers by utilising his Jewish cousinhood in Vienna, Prague and his birthplace, Bohemia. He claimed ancestry with the classical composer Felix Mendelssohn, though all Mendelssohns are of Jewish ancestry and claim cousinhood due to the endogamy of the closed Eastern European shtetels. Mendelssohn's aunt, Miriam Warner, was a West End theatrical and musical agent, as were his cousins Jack Somers and Ernest Warner in Tottenham.
