The 'Far Far Better' song

This movie is okay, it's pretty entertaining and I quite enjoyed it as a kid, but it's not brilliant. But I always thought - and especially think it now - that the song the Father sings at the end 'Far Far Better Thing That I Do Now' was absolutely incredible; it sent shivers down my spine. It seemed a bit out of place in the movie, actually.

It's a shame that the soundtrack doesn't seem to be available. :(
