Merlin & Robbie Singing!
Microsoft Agent Singing Demo -
Microsoft Agent Scripting Helper (MASH) and Music Scripting Helper (MUSH) were used to make the MS Agents sing. Windows 98 and ME were preset to use MS Agent. XP requires a bit of adjusting to enable it as does Vista. I don't think anybody has much interest in MS Agent anymore but I always enjoyed creating with it. Examples at http://tinyurl.com/grabshot
