This Week in Billboard Chart History: 50 Years Ago, Petula Clark Topped the Hot 100 With 'Downtown'

Your weekly recap celebrating significant milestones from more than seven decades of Billboard chart history

Jan. 19, 1980
Michael Jackson crowns the Billboard Hot 100 with "Rock With You." The song marks his first of nine No. 1s in the '80s, the most of any artist during the decade.

Jan. 20, 1990
Two decades into his career, Rod Stewart scored his first Adult Contemporary No. 1 at last. On this date 25 years ago, "Downtown Train" chugged to the top of the chart.

Jan. 21, 2012
Days-old Blue Ivy Carter receives featured credit on dad Jay Z's "Glory." As the song, featuring her cooing, debuts on Hot R&B/Hip-Hop Songs at No. 74, she becomes the youngest person ever to appear on a Billboard chart.

Jan. 22, 1994
Playing off the movie The Three Musketeers, Bryan Adams, Rod Stewart and Sting share the Billboard Hot 100's top spot for the first of three weeks with the film's hit single "All for Love."

Jan. 23, 1965
As Chart Beat reader Pablo Nelson notes, currently Mark Ronson and Bruno Mars rule the Billboard Hot 100 with "Uptown Funk!" … 50 years after Petula Clark's geographically-opposite "Downtown" reigned. Clark's debut No. 1 (which jumped 4-1 on the Jan. 23, 1965 Hot 100) is technically not about downtown or uptown, but midtown … Manhattan. The song's writer, Tony Hatch, wrote it just north of Times Square during his first trip to New York, enamored by the "music of the traffic in the city … where the neon signs are pretty."

Jan. 24, 1998
As the movie dominated at the box office, the Titanic soundtrack began its 16-week Billboard 200 rule. The set and the title it replaced at No. 1, Celine Dion's Let's Talk About Love, both include the film's signature ballad, "My Heart Will Go On."

Jan. 25, 1992
Color Me Badd collected its second Billboard Hot 100 No. 1, as "All 4 Love" followed prior single "I Adore Mi Amor" to the top. The Bryan Abrams-led group will join fellow '90s-hitmakers All-4-One and (former Billboard publisher!) Tommy Page for a love song-laden "Retrolicious 2015" concert in Singapore on Feb. 7.
