John,
No trouble loading your piece (both your LINKS are the same, so clicking on either will load it).
I am fascinated by your comment:
The song is in 4/4 time but the chorus is a waltz. Most people just know the chorus.
I'll Be Your Sweetheart is a 1945 British historical musical film directed by Val Guest and starring Margaret Lockwood, Vic Oliver and Michael Rennie. Listening to the below from the film, I can see (hear) where the 4/4 time comes in. And you're right. The basic melody we all know
is sung as a waltz.
' I'LL BE YOUR SWEETHEART ' sung by Margaret Lockwood.Here is a version by Foster & Allen.
Foster & Allen - I'll Be Your SweetheartIn both cases the song is sung a lot faster than the tempo
you chose, John.
