There were quite a few cues from The Chronicles of Narnia: Prince Caspian that were missing from the OST. Some seem to be almost exact copies of cues from the first film (namely Trumpkin's rescue near the beginning and Lucy's dream) so that's no real loss, but others are sorely missed--particularly the first part of the night raid and the alternate take of the ending song, "Call".

Does anyone know of or have access to a complete or bootleg score?

Yes, I too am looking for this.

I'm looking for it as well.
