Can you tell me the correct lyrics to "Deck Us All With Boston Charlie?"

Maybe can.  There are many versions of this revered, classic carol and fist fights have been known to erupt when one person defends the sanctity and accuracy of the one he or she learned at Mommy's knee.  People have been hospitalized as a result of such disputes, which is a heckuva thing to happen at any time of year, and especially around the holidays.  That said, we can at least direct you to what scholars tell us is the most popular.  Here it is...but we assume no responsibility if a rival Boston Charlie caroller takes issue with you and comes out swinging.

Where can I find those cute little plastic figures of the Pogo cast?

Jeepers.  Where can't you find them?  They came with various brands of Proctor & Gamble detergent in 1969 as part of a tie-in to promote The Pogo Birthday Special which aired on NBC that year.  Rumor has it Mr. Kelly wound up being a lot happier with the plastic figures than the special.  He personally sculpted the originals of the six: Pogo, Albert, Churchy, Howland, Porkypine and Beauregard.  You can see Beauregard at right, horrifyingly shrink-wrapped to a box of Biz.  There are washerwomen who've had nightmares about finding themselves in the same predicament.  Anyway, they turn up all the time on eBay and in antique toy catalogues, so don't go paying a lot for them.  (One of the guys who maintains this site found his Pogo lying on the ground in the parking lot of his bank.  You might try looking around the parking lot at yours.)    

Where can we find those cute little non-plastic figures of Pogo and Albert?

Ah, those are nice.  Stop looking around the parking lot of your bank for the plastic ones and order these from someone like Bud Plant.  They're part of the Dark Horse's "Classic Comic Characters" series which issues fine, if small, statuary of the superstars of the funny pages.  Pogo is statue #24 while his pal Albert Alligator is #25.  The little figures were sculpted by Yoe! Studios working from sketches by (and under the quality control of) Carolyn Kelly and each comes in a decorative tin box and includes a pinback button and a biography of Walt Kelly.  If you want one, you'd better hurry since they were a limited set of 600 and there aren't many left.

Can I use pictures of Pogo and his friends on a project we're working on?

For information on that, you'll want to read this page.  It'll tell you most of what you want to know.
