It's hard for me to believe that so much time has passed when I see this video by U2.
MTV had just gone on the air in late summer 1981 and I was glued to the channel. This was the song that caused them to enter my radar screen for the first time.
Check out how young they are. I would not recognize The Edge with all his hair, and Larry Mullen, Jr. looks about 17-years-old here.
