Saw the half-time show.
I thought Gordon played well with canned music besides his gtr and voice. Being about 74 yrs old, I thought it went well for him. Miss the huskiness of his voice, however. It's thinned out or they gave him a bad microphone.
Justin was fine. Not surprised he was booed. Most people at the game would have been 25+ yrs old - way past his normal audience and wouldn't care for his segment of the show. His handlers should have known the live demographics for the Grey Cup would not be skewed in his favour. Maybe they thought the TV exposure was more important.
