climbing that stairway to heaven...

so Zep got off.
I like them and Spirit so I guess it all works out in the end.
Here are 4 songs that share the same or nearly the same chord progression and yet they are all different.
Stand By Me- Ben E. King
I Will Always Love You- Dolly Parton
Wagon Wheel- Old Crow Medicine Show
A Roving- Doc Watson

so there ya go.
