I grew up listening to Adventures in Odyssey. Boen's Blackgaard character was the ultimate villain. The first time I heard his voice in a Monkey Island game was as Charles L. Charles in the demo for Escape From Monkey Island. It was a great surprise. Then I heard two other Adventures in Odyssey voice actors in Curse: Allan Young (who plays Jack Allen in Odyssey) voiced Haggis and Dave Madden (Odyssey's Bernard Walton) played Dinggy Dog. Jess Harnell (who plays a more recent Odyssey character called Wooton) does several voices for the MI Special Edition including one of the Fetuccini circus brothers. The world of top talent voice acting is a small one indeed!
And about Boen's retirement...I thought it would be a lost cause for them to get him to record for a Revenge Special Edtion, but the fact that Tell Tale was able to get him to re-record for Tales is a good sign.
