Thanks, Masato.It's hard to see if they are the same, since there is no tune for this one at the Park Choir site. Since so many of their pieces do not show up in the index of songbooks I have, it's hard to tell what their sources are. Hopefully as the overall project shapes up we will be able to invite them to come discuss some of these with us!
(Of course my index is not complete yet, so maybe this and others will turn up as more indexes come my way.)
