Let's make this birthday one to remember.

90 years old (Born on August 25, 1934)

Happy Birthday, Bill! You've given us the definitive history of country music with your groundbreaking book "Country Music, U.S.A."—clearly you have enough wisdom and charm to fill a honky-tonk jukebox twice over. Your scholarship sings louder than Johnny Cash at Folsom; if documenting country classics were an Olympic sport, you'd surely win gold every time.

As you celebrate another milestone, we're tempted to serenade you "Happy Birthday" accompanied by banjos and fiddles. But considering how exhaustively you've chronicled their history, we're sure you'll already know every lyric (and probably corrected us halfway through!). Here's wishing you endless laughter, joy—and plenty more verses to explore!
