Does anyone know what happened to these songs on Return of the Jedi's soundtrack

Hey, I'm curious but does anyone know what happened to the song Victory Celebration on the Return of the Jedi's soundtrack album. I can't find it on any streaming site nor to buy, The same goes for the track that plays when Luke and Vader fight, you know the ghost'll chorus that play's as Luke finally attacks Vader. I swear I remember them being on the soundtrack a couple of years ago, but I couldn't afford to get it at the time.Edit: Special Edition version by the way. I thought since both ending songs have different names (Victory Celebration is the name of the special editions) I didn't need to specify. via /r/StarWars http://bit.ly/2WBVryo
