I Wish It So is the beautiful surviving tune from Marc Blitzstein's unsuccessful 1959 musical Juno, based on Sean O'Casey's play Juno and the Paycock.

There's a beautiful rendition of the original by Dawn Upshaw, but I haven't tried to preserve that harmony.

If anyone wants a copy of Blitzstein's original piano score, send me a PM and I'll email it to you in a PDF.

Meanwhile, I've rearranged the tune with jazz changes and cut the intro and outro.

The score for my arrangement is at http://www.freejazzinstitute.com/sho...4803_engelbach.

I Wish It So-Rev JE - Marc Blitzstein
