Let's make this birthday one to remember.

77 years old (Born on June 20, 1948)

Happy Birthday to the legendary Alan Longmuir! From rocking tartan trousers and laying down unforgettable bass lines with The Bay City Rollers, you've kept us dancing since the '70s. Your grooves made "Saturday Night" feel like every night of the week!

And let's not forget your cinematic charm in "Burning Rubber." Who knew our favorite bassist could burn up both stage and screen? Whether you're spinning records or tires, you always keep things rolling smoothly.

Alan, here's wishing you a birthday filled with laughter, music, and perhaps fewer plaid fashion statements—but hey, who are we kidding? Keep rockin' that tartan forever!
