In 1975, facing competition from the growing Canadian operations of McDonald's, the company launched what was to have been a temporary advertising campaign starring an orange-clad mascot, The Great Root Bear. The bear and the tuba jingle that accompanied him became a long-running campaign (the tune, entitled "Ba-Dum, Ba-Dum", was released as a single by Attic Records, credited to "Major Ursus", a play on Ursa Major or "great bear"). The famous Canadian composer and B.C. Hall of Fame winner Robert Buckley helped compose the song. The mascot was so successful that he was eventually adopted as the mascot by the American A&W chain as well. The famous tuba jingle was played by famed Vancouver jazz, classical and session trombonist Sharman King. King also did the ads for the "Book Warehouse" chain of discount book stores, which he owned.
