One that most of us know well has an odd ball number of bars, but it isa pure sonata form, AABA song. Hoagy's tune, "New Orleans" has fours bars, repeated, a bridge of four bar, then a reprise of the second four bars Always thought those Hoosiers were a stingy lot! But Hoagy made up for it with Batimore Oriole so all is forgiven. Don Ingle
