On this date in 1983, The Police performed in San Diego with a band that was almost as popular as they were in Southern California at that time. On the pass you see below, the "OB" stands for Oingo Boingo, who were one of the opening acts.
That's great for Oingo Boingo, but the rumor was that they replaced a band that the Police very much wanted and had toured with before. The band was XTC, but XTC stopped touring during the 1982 tour, and sadly never toured again because of lead singer Andy Partridge's extreme stage fright issues.
So Oingo Boingo took advantage of their opportunity and vastly widened their audience, subsequently getting them an opportunity down the road to record the title song for the movie "Weird Science"...and then Danny Elfman was off to the movies...
