George Strait continues his farewell (sort of) tour throughout America and this past Saturday night was in Philadelphia, Philadelphia with guest Martina McBride.

As has been his custom throughout the tour thus far with his opening guests, he invited Martina back after her set to sing a couple of duets with him.

The two songs they performed were the Johnny & June Carter Cash hit "Jackson" along with the George Jones/Tammy Wynette classic "Golden Ring".

Both songs were spot on and you can tell the chemistry between these two great singers.
