I just listened to a MIDI rendition of this, "Blessed Savior, thee I love," Spanish Hymn.
To me, it has the same tune as "Twinkle, twinkle."
But I agree, "Twinkle, twinkle" is a classic.
I don't know if you can catch this, but here at least is some more information.

If you go to the web-site, and then find the file, it should be able to load and play automatically.
Try singing Twinkle, Twinkle to the music.
