Growing up, I vaguely knew about them. They didn't get a lot of airplay during the 1970s, at least in the Boston area. But they utterly exploded when the "Hi Infidelity" album came out.
I was in Marine Corps boot camp in Parris Island most of early 1981, when that album was become a major hit. When I graduated from boot camp and got to listen to the radio for the first time in months, "Keep On Loving You" was one of the first songs that played on the ride to the airport to go home and I was immediately hooked. Even today, that song takes me back to my graduation day of boot camp and the beginnings of the Reagan presidency. Other songs I remember from the trip home was "Bette Davis Eyes" by Kim Carnes, "Angel Of The Morning" by Juice Newton and "Rapture" by Blondie. All of them instant classics from the first listen.
Nice memories.
"Nice Shirt!"
Same for me. Joined the army January 20, 1981.
