AC/DC were one of the first bands I really got into after my dad gave me his copy of If You Want Blood You've Got It on tape. Spent a lot of time looking up ye olde tabs for Riff Raff and Let There Be Rock among many other tunes. He had a chance to see them in 1995 during the Ballbreaker tour but didn't and regretted it ever since. We finally got to see them in Glasgow during the Black Ice tour. I only just nipped in past Kirriemuir a couple weeks ago to see the Bon Scott statue as well.
He had dementia for a number of years and unfortunately it's only a matter of time at that point. Truly one of the most influential rock bands ever. RIP
