Hey Jim!! Of course I would LOVE to tackle this one -- unfortunately there is an approval process that needs to happen with the music publishers in order to teach the song on the site. I know GT is always working on trying to get more Zep, so keep your fingers crossed!
BTW the Pete Townshend Artist Study is approved and filming next month!!! Look for it to make it's way onto the site in the coming months!
