Ramones
The challenge here is to write about a song I liked from the 70s. There are a lot of songs I liked from the 70s. A lot of the music from the 60s Woodstock era trickled over into the 70s, but that music doesn't really identify the 70s.
Real 70s music has to be either Disco or Punk because they were born in the 70s. I never really liked stayin' Alive or Saturday Night fever. So I am going to have to go with the Romans. Here is Blitzkrieg Bob:
Have you ever seen such an ugly group of boys in your life?
I was just a little kid when this came out. I heard it from my mom's brother because my dad was not into punk at all. I will never forget these guys. To me they represent the seventies. Although Led Zepplin did make some music in the 70s they were a 60s group. There are no other contenders in my book.
