I'm also a fan of some of Willie's music, which is why I don't feel the least bit shy about saying that he ought to stop singing and concentrate on something else for awhile.
It ain't about Willie's age, it's about the mileage on his voice.
And John, if you don't know who Toby Keith is, in order to contribute something meaningful to this thread (rather than a reactionary ad hominem attack on another poster), you might want to find out about his politics, particularly his antics of late. Why should anyone pay attention to your opinion here, when you profess to know nothing about one of the two musicians being discussed in this thread?
