Exactly 47 years ago—November 21, 1970—"I Think I Love You" and the Partridge Family flew to No. 1 on the Billboard Hot 100 and nested there for three weeks.
Chewing on that piece of bubble gum history today, however, is bittersweet. David Cassidy, the then 20-year-old teen idol who sang the fictional TV clan's debut single and biggest hit, is now 67 and critically ill, suffering from liver and kidney failure.
"Unfortunately David is very sick," writes son Beau Cassidy, 26, in a message on the singer's official website. "However he is getting the support he needs, surrounded by the people he loves most."
"I Think I Love You" was released in August 1970, a month before the premiere of "The Partridge Family" on ABC. The upbeat number was played just twice during the sitcom's first season, but that was enough to satisfy millions of adoring girls who fantasized that Cassidy's giddy profession of love was intended for their ears and hearts only.
He sang, "I think." But they knew for sure.
