Probably one of the most famous rock songs ever – try here. It was probably one of the fist rock songs that I learned to play on guitar when I was a teenager. there was a movie I remember seeing- I think it was the Blues Brothers and in the store there is a sign saying ‘No Stairway To Heaven’. Wonder how many times music shop owners have had to listen to a kid trying to play it in their store.
If you would like to learn to play the song, there are online lessons over here

Jimmy Page was such a great rock guitar player, but what he perhaps isn’t recognised as much is that he was also a great blues player, and so many of the riffs that he came up with had their roots in the blues.
