Oh, Lawd, I'm on my Way (from 'Porgy and Bess') - George Gershwin

For Baritone, Choir and and concert band.

Gershwin's opera 'Porgy and Bess' contains many songs that have become popular in their own right, becoming standards in jazz and blues in addition to their original operatic setting. One of those is the 'Oh Lawd, I'm on my way' which is sung by Porgy and the choir at the very end of the opera.
