Let's make this birthday one to remember.

78 years old (Born on August 20, 1947)

Happy Birthday, James Pankow! You're the only trombonist we know who can slide effortlessly from Chicago to Three Dog Night, groove with Toto, and still keep up with the Bee Gees' falsetto. Your brass arrangements have been so iconic that even air guitarists secretly wish they played air trombone.

From "Saturday in the Park" to touring worldwide stages—your music has become timelessly cool. You've given us decades of hits without missing a beat (or a note). Here's hoping your birthday celebration is as legendary as your horn solos—and may you continue sliding into success for many more years!
