NOT John Krasinski's ringtone

This is not the ringtone that John Kransinski has in the New Era commercials but it's the first tune I could think of that even begins to compare.  The notes are very similar-- both go do-re-mi-do-la-- but the rhyme of the music is decidedly different.  I know this song because I watched "The Boondock Saints", and the only other similar music I own is the Riverdance soundtrack, which features more, well, dancey music.
