I'm not sure where this topic actually belongs, so I thought I'd put it here, where it would be seen by the most people.

Here it is:

How do you play the intro part to the song Baba O'Riley by the Who? It sounds to me like it could be a guitar with delay, but it seems to sound almost like a keyboard.

Is anyone here able to play this with a guitar? Perhaps you have invented your own arrangement/interpretation of this song. If so, please share...
