Here's my take.....for what it's worth.
Billy Joel was real good.
Willie Nelson struggled through the words of America the Beautiful.....and plainly heard was a 'prompter' giving out the words of the song......line by line.......to the entire gang of dummies, who probably never heard of the song before tonight!
But I give them credit for their effort and feel they mean well.
Tom Petty was my favorite and I thought Mariah Carey did a good job, other than that......
