What games from the 80s were these?

I have answered dozens of this type of question before but now I'm curious about two that I'm trying to remember based on their music. It's a long shot but here goes.

Both are from the mid to late 80s, likely the Commodore 64 or Amstrad, or possibly the Amiga.

1. It was a platform game based around an old mansion? I think there was a slight horror theme. All I can remember is that the music was the "Dance of the Knights by Dru Masters" (It's used in the Apprentice - http://www.youtube.com/watch?v=TTufAS4eVp8). You started outside at the top of the house and made your way down, landing on some spiked railings would kill you. It was in colour rather than monochrome (I remember playing the Rocky Horror Show around the same time).

2. I can barely remember the game, only that the music was "The Entertainer", by Joplin (http://www.youtube.com/watch?v=fPmruHc4S9Q). I remember an alley for some reason, though I'm fairly sure it's not Alley Cat. It was either a target shooting game or the player was an actual cat.
