The lullaby of Malvina's that I like best is Morningtown Ride, and while it's not (at least doesn't appear to be) in the database, it IS in that other bastion of folksong words; Rise Up Singing.
A while back, Joe entered some of her songs, was that one, Joe? I'll look some more, and if I can't find it, I'll post it. It's got the line in it,
"Rockin' rollin' riding,
Out along the Bay
All bound for Morningtown,
Many miles away
Blessings,
Barbara
