I guess Kruk should send you a letter of apology, since he, along with the rest of the world, is expected to know who Geddy Lee is. Not everyone is into music and who plays with which band like some are, in fact most people couldn't name all the members of any one band, let alone a specific one.
As for Kruk's talents, or lack of same, as a baseball commentator, I cant say, because I've not heard him yet, in fact I don't even have a clue if he is a pre-game show, post-game show or in-game commentator. Is it something every Nats fans is supposed to know, or is it OK for an out-of-towner to not know everything that goes on the air in DC?
BTW, without looking it up, do you know who John Entwistle is?
