Since today is Wednesday, February 21st, I want to go back, way back, to 1972.

On this day in 1972, Led Zeppelin released the song 'Rock And Roll', from their album 'Led Zeppelin IV', as a single.

The song was released on a 7 inch single in the United States along with the song 'Four Sticks'. The song reached number 47 on the charts.

The song was written when they were writing the song 'Four Sticks'. They were having trouble finishing it and through a jam session of trying to complete it, 'Rock And Roll' was born out of that session.
