It’s not unusual to be accosted several times on the way from Lerner up to the steps by earnest Bible studyers asking whether one is a Columbia student and/or Christian. Bwog usually thanks them politely and walks on, reminding itself to dodge the next time one homes in like a heat-guided missile. But it couldn’t help but raise its eyebrows at the quintet singing Amazing Grace on College Walk this afternoon, especially since it included two performers from the Varsity Show (here and here), not generally known for its good family values.

At least they sing well.
