Bob Jenkins never forgot the Winnebago ad. It ran during a football game while he was at his sister's house for Thanksgiving.
"I remember sitting there thinking, '50 million people are hearing my music right now,' " Jenkins later recalled in an interview.
That was one of his first advertising music tracks. But Jenkins' tunes were soon blasting from television sets across the country, from doo-wop extolling breakfast sandwiches to rock 'n' roll selling hair dryers.
Jenkins, a prominent big-band trombonist who became an award-winning composer of commercial music, died Aug. 8 of heart problems. He was 80.
The Minneapolis native and Roosevelt High School grad first made his mark as a freelance musician, playing around the world with big-band titans like Woody Herman, the Glenn Miller Orchestra and the Tommy Dorsey Orchestra. He recorded tracks in New York studios, including elevator music he would hear in elevators years later.
At 23, he was playing lead trombone in a recording studio alongside Urbie Green and Bill Watrous — two heavyweights of the instrument.
"He said, 'This is about as good as it gets for a trombone player,' " his friend Kent Saunders said, adding that Jenkins decided it was time to try something new.
So he moved to Omaha — and later Minneapolis and Chicago — and began writing music. Some compositions were scores for "industrials," films that corporations produced to energize their employees at annual conferences. But he became best known for commercials.
