WAITING ON YOU
In an interview, Page said he used the Digitech Whammy Pedal on this
quite a bit so he wouldnt be restricted to a slide tuning,
so this is all an approximation of what it is.

I think thats all you pretty much need to piece it together.
I cant remember the solo, but it simple and very melodic.
