TOLEDO...

This is a little bit complicated, but very easy and very Googlable, so try and refrain.  I want X, Y, Z, A, B and C.

This book of short stories was written by Del James. It features an intro by X, who is the lead singer of Y. It includes the story 'Without You', which inspired B, a song by Y.

A, B and C are three songs which appear on the double-album Z by Y. Their music videos form a trilogy of sorts which X claims was inspired by the book, although fans often argue about the order of the songs in this trilogy. This trilogy has been called the Illusions Trilogy by X.

Additionally, B and C are two of the most expensive music videos ever made. The production cost for C's video was over 4 million dollars and the video was widely panned when it first came out for being too extravagant - many critics took this as a sign of X's growing ego.
