76 years old (Born on September 29, 1948)
Happy Birthday, Mark Farner! You're still rockin' harder than a locomotive—Grand Funk Railroad style. From "We're an American Band" to "Some Kind of Wonderful," your riffs have kept generations grooving and air-guitaring shamelessly in their living rooms.Even after decades on stage, you continue to prove that age is just a number—and apparently yours comes with unlimited guitar solos. May your birthday be filled with as much energy and excitement as the legendary Shea Stadium concert back in '71. Keep turning up the volume; you're truly some kind of wonderful (and timeless). Rock on forever, Mark!
