Funny that you mentioned that band. One of my friends from the park who is at least 20 years older than me was sporting an AC/DC cap this morning. I chuckled.
Good for your friend-I’ve been a fan since the beginning-I’ve put the greatest hits tape or CD in every vehicle of mine since about 1980-something-it is what I crank up and sing with when I’m stressed, and it has been the death of many a stereo speaker...
