Malcolm has the following embedded in his midi:

Sun-days as a rule, Us kids went to Sun-day school
And Mr-s. Ad-lam said, An-gels stood round our bed
To keep us safe from dark, right through till day be-gun,-
And we used to lie a-wake, just to try and see one,
And though we nev-er saw one an-y-where,
We heard them soft-ly sing-ing in the air.

Knowing Malcolm - this probably came from sheet music. Don't know if he still has further lyric if he ever did.
