Happy 78th birthday, Brian Johnson! Can you believe it's been another trip around the sun for you? You may be one year older, but we all know you still rock harder than any 20-year-old out there. Wishing you all the best on your special day and hoping it's filled with plenty of good music, good friends, and maybe even a little bit of mischief. Cheers to another year of living life to the fullest and making us all want to age as gracefully as you do. Here's to many more years of rocking out!
