Day Thirty-nine - Shooting the "H". . .

Well, we're about four hours into the Blizzard of 2013 and I still have power! If you are reading this, I guess you do as well!!
So here is today's "H" challenge - a two-for-one. . .

For the musicologists out there:Who immortalized the MBTA with a classic folk song in the fifties? Song and Artist, please.

Well, Day 38 was an actual WWII Gas Mask! Here are the correct responders: Mike P., Ted, Phil, Mariann, Milt, Tony, Michelle, Peyton, Steph, and Mike Di. 

Only EMO and Milt knew the names of the pitcher (Tomorrow) and the catcher (Today) from the "Who's on First" routine. It's a classic with superb timing - catch it on YouTube.
