Willie Nelson -- All Smiles After Medical Scare

Three days after canceling a performance in Denver after suffering from "breathing problems," music legend Willie Nelson resurfaced looking happy and signing autographs in New Orleans on Wednesday.

On Sunday, the 79-year-old was hospitalized because he was having trouble breathing "due to high altitude and emphysema."

Good to see Willie on the road again.
