I have seen a game with fan add ons that falls directly into the scenario HallowKnight mentions. The Minstrel card says explicitly the Maiden and Princess so that's all he can charm (and not the female Sage's Apprentice that came up). Anything else is an attempt to interpret beyond set game rules and a power grab not in the spirit of the game.
The concealed pouch has caused other problems in my 2e days. One discussion involved a ruling that the only objects (magical especially) that were "active" were ones on the character. If the pouch were on a mule or horse and cart (and especially if it were empty), would it still be concealed? We were never able to reason it out, so we stuck with what was on the card - it can't be stolen, but anything else was allowed when it wasn't "in use" by a character.
Rexaroo... it looks like you'll have to set a house rule of your own agreeable to all members of your group.
