That's in the top 5 for sure. Who didn't learn that one? FWIW
I had buddies working in music stores during that time frame, and they were ready to put a gun to their head if one more 14 year old plucked his way through the intro to “Stairway to Heaven” at 95 decibels...
Every cover bad in every club played “Smoke on the Water”.
I hate the song, but it has one of the most recognizable intros of straight ahead top 40 rock.
