i do- if you are indeed talking about waiting for the T down in the station.
will it be the banjo guy?
will it be the accordian guy?
will it be the guy who mostly sings beatles and elton john?
i like the surprise because all the people who play down in the station are good and there is a pretty good rate of variety down there.

when it comes to up top in the square, there is not as much variety and not as much quality, either. those are two separate things, though.
