Current Version: 1.4
In version 1.4, the score is correct, but the parts are missing some of the hairpin crescendos and decrescendos - you may have to ask your players to write those in. Again the score is correct, only the parts are missing these markings.
If you happen to have a version older than 1.4, please contact me and we'll work something out. Please note that that title has been changed from Overturus Interruptus to Interruption Overture.
