Add the Pugwash theme, aka the Trumpet Hornpipe. I've checked this against YouTube and the first episode, and corrected an obvious wrong note in Paul Hardy's version. But I've kept his descending triplets in the last line of the B tune - the original has the same note, with descending chords, but changing the triplets to remain on G doesn't sound right.
