Late follow up re easy part songs for family singing

For some reason Donna's answer to my question about singing part songs with my
children never got to my server, or I deleted it by accident, or something. I
just ran across it on Google when looking up something else.

"Alfred publishing has several wonderful collections of partner songs-where
two melodies are sung at the same time-a step up from rounds and a lot of
fun to sing.

Plank Road publications (www.musick8.com) has a music magazine which comes
out 5 times a year, with wonderful 1,2, and 3 part songs designed for
childrens voices, which would be good for family singing as well."

This sounds great, thanks so much!
