The All True Adventures of the Agents of M.O.M.M.Y. and D.A.D.D.Y

While watching the Three Amigos during the part where they summon the Invisible Swordsman by the Singing Bush, the Queen began singing with the bus.

QM : He's a colly food fellow, o he's colly food fellow.
Agent of D.A.D.D.Y. : What are you saying?
QM : He's a colly food fellow.
AoD : Colly food fellow?
QM : Yep, colly food fellow.
AoD : What's that?
QM : It's English.
AoD looking confused.
QM : You don't know it because it's only for kids like me and the Captain.

Then the singing stopped and the Queen continued to watch the movie.

According to guiness, He's a Jolly Good Fellow is the second most popular English song. Happy Birthday to You is #1 and Auld Lang Syne is #3.
