(Debuted February 25, 1984, Peaked #8, 17 Weeks on the Chart)
No blog that covers the 1980s would be complete without a mention of Tracey Ullman's influence. Her TV show on Fox during the early days of that network was highly-acclaimed and introduced us to The Simpsons, a cartoon that is still with us over 20 years later. But prior to her American acting breaktrough, Ullman managed to get a Top 10 pop hit that certainly sounded like it came out of the bubblegum era of the 1960s.
That said, it would be remiss to mention "They Don't Know" without mentioning that it was written and originally sung by Kirsty MacColl in 1979. MacColl sings backup on this version as well, even belting out the high-pitched "bay-ay-bee" at the end of the instrumental bridge. The video is notable because Paul McCartney makes a cameo appearance at the end. Ullman was appearing in McCartney's film Give My Regards to Broad Street at the time and he was glad to help her out.
