I would suspect a christmas carol, because theyve been around for a woopteedoo of a long time. Like 'we wish you a merry christmas' billions of children (and parents forcefully) sing that on an annual basis (:
I think it would be Happy Birthday to you
I would say hush little baby, I bet trillions of parents sing it every night.:)
I think it would be a toos up between Happy Birthday and Some Christmas songs and Hymms
I came across this question once in Trivial Pursuit- it is Happy Birthday.
In America? Or just in general? The National Anthem is a big hit...
In the usa i would say, the star spangled banner.
- Happy Birthday
Most sang song got to be happy birthday
