Staus quo single 1970 quo play it standard tuning weird this suits open E tuning thought aye would put it. key of G the chabdges up a semi tone ie G# at the end. works well if you tune 5th up to B hence 6th=E 5th=tune up one step ie to A to B works fine could play lot of quo like this, makes a bit easier on the fretted hand. anway enjoy
