My son came in and asked me why I was playing "that song from Lazytown," so this is the same one. He then recalled -- and sang -- the rest of the lyrics.
This was the first ever episode of Lazytown I ever saw, and I thought it was the greatest kid's show ever. Then I learned that the Pirate theme was just the one episode.
BTW, I have been on the computer (again) for about a half-hour now, and I have that window open, which has played and replayed that brief Pirate clip about a hundred times now.
"Yahr har, Fiddle dee dee, being a pirate is alright to me..."
I gotta get that as a ringtone...
