On this day in music history: August 23, 1975 - “Fallin’ In Love” by Hamilton, Joe Frank & Reynolds hits #1 on the Billboard Hot 100 for 1 week. Written by Dan and Ann Hamilton, it is the biggest hit for the soft rock band from Los Angeles, CA. Band members Dan Hamilton (vocals, guitar), Joe Frank Carollo (vocals, bass) and Tommy Reynolds (vocals, keyboards, percussion, guitar) have all previously been members of the instrumental studio band The T-Bones who score a big hit with the instrumental “No Matter What Shape (Your Stomach’s In) (#3 Pop) in February of 1966. The T-Bones disband in 1967. The band reform 1970 under the name Hamilton, Joe Frank & Reynolds signing with Dunhill Records. They score another top five hit with "Don’t Pull Your Love” (#4 Pop) in July of 1971. Original member Tommy Reynolds leaves the band in 1972 and was replaced by keyboardist Alan Dennison, though they keep the “Hamilton, Joe Frank & Reynolds” name. In late 1974 they sign with Playboy Records, a new label formed by Playboy Magazine publisher Hugh Hefner. For their first release, they choose the lush ballad “Fallin’ In Love” written by Hamilton and his wife Ann. Released as a single in late April of 1975, it is initially slow in taking off, but once it takes hold it makes a quick ascent. Entering the Hot 100 at #89 on June 21, 1975, it climbs to the top of the chart nine weeks later. The band scores one more top 40 hit with the follow up “Winners And Losers (#21 Pop), before they break up in 1976. Years later, "Fallin’ In Love” is the subject of a lawsuit when Playboy Enterprises sues R&B singer/rapper Drake, his label Cash Money Records and distributor Universal Music Group when he samples “Fallin’ In Love” on his hit single “Best I Ever Had” without acquiring the proper copyright clearance. “Fallin’ In Love” is certified Gold in the US by the RIAA.
