The grand old man of British jazz, trumpeter and bandleader Humphrey Lyttelton spearheaded the postwar trad jazz revival before renouncing the movement in favor of more contemporary and restless creative vision. A larger-than-life figure, he also excelled as a writer and cartoonist, and for decades was a fixture of radio, serving as the hilariously deadpan host of the long-running I'm Sorry, I Haven't a Clue. Born in Eton on May 23, 1921, Lyttelton was the product of a distinguished and wealthy family -- a lifelong jazz enthusiast, he received his first trumpet at age 15 and formed a band with some Eton College classmates. He also studied military drumming under a former Coldstream Guards drum major and joined the school band as a percussionist. Lyttelton enlisted in the British Army on D-Day and saw combat in Italy -- on leave in London he sat in with local jazz bands, and upon returning to civilian life in 1945 he enrolled at the Camberwell School of Art. In March 1947, he signed on with semi-professional trad jazz combo George Webb's Dixielanders; when Dixielanders clarinetist and professional cartoonist Wally Fawkes was promoted to write and illustrate a full-fledged daily strip for The Daily Mail, Lyttelton was tapped to fill Fawkes' previous position sketching "column-breakers" -- i.e., humorous or decorative drawings inserted into the text. He also reviewed jazz and classical recordings for the newspaper, and later scripted the Fawkes-drawn strip Flook as well.
