"Comedian Harry Stewart, born October 21, 1908 in Tacoma, Washington, and who alternately recorded and performed as the Swede, Yogi Yorgesson, a character first developed as a crystal ball-gazing Hindu mystic from Stockholm on the Al Pearce radio show from 1934 to 1937, and as Harry Kari & His Six Saki Sippers, would probably have long been forgotten by the 1970s after his tragic death as the result of a car accident at age 48 on May 20, 1956, were it not for the efforts of Dr. Demento and two fellow Washingtonians, Stan Boreson and Doug Setterberg.
For his part, Dr. Demento, born Barret Eugene Hansen in Minneapolis on April 2, 1941, always made sure Stewart's two big 1949 seasonal hits as Yogi Yorgesson with The John Duffy Trio, I Yust Go Nuts At Christmas, a clever parody of The Night Before Christmas (# 5) and its B-side, Yingle Bells (# 7) on Capitol 57-781, and his one as Harry Kari - Yokohama Mama (# 22 in April 1953 on Capitol 2392 b/w Yes Sir, That's My Baby) were played often on his syndicated radio show as well as appearing here and there on his many album salutes to the novelty hits of the past."
