It may be only a symbolic gesture, but my estimation of Stephen Harper just went up a bunch.
I don't agree with his policies, I don't like his political methods, and I can't conscionably support his party, but it's fantastic to see that he can be spontaneous once in a while and that he has some respect for the arts. Not to mention the fact that he can be a little self-deprecating too, in his choice of songs.
Besides, I've played the piano since I was four. So, even if it was intentional, he went somewhere that I -- and a lot of other people too, even if they play or have played different instruments -- can identify with and appreciate. Harper might be quiet and reserved, to the point of coldness at times, but I'm glad to see he can go beyond that.
And damn, he can sure as hell carry a tune.
