And Pietro, eh? Good stuff.
Yes, Pietro Yon was organist at St. Francis Xavier for about 12 years before he went to St. Patrick's Cathedral. While at Xavier, he composed "Gesu Bambino". Of course he wrote reams of both choral and organ music (and very tricky stuff too!) which is now largely gathering dust.
His brother, Constantino, was organist across town at St. Vincent Ferrer. He composed too - though output was less, and lesser known.
We still use some of Pietro's stuff here. Yes, the organ parts can be a challenge...
