Castle Walls Live Mashup - DeYoung and Gowan Duet

I like them both. And Castle Walls is one of my favorite tracks.
While listening to "The Grand Illusion/Pieces of Eight Live" album that Styx just recently put out, it suddenly occurred to that I had to do this...and so I did it.
This is the first time I've ever done a mashup, usually I do Medleys. I worked very hard to make everything sound as clean as I could, but there may still be mistakes. I'm limited by my freeware and sometimes by the musical tracks themselves.
The Dennis DeYoung track is from his 2004 live album "The Music of Styx: Live with Symphony Orchestra". The Styx track is from their 2012 live album "The Grand Illusion/Pieces of Eight Live".
The pictures are screencaps I took from my DVDs. The Styx caps are actually from their performance of "Castle Walls". Sadly, Dennis DeYoung's perfromance of "Castle Walls" was not included on the DVD release. The caps of Dennis are from him singing other songs.
No infringement intended. No profit made.
Hope you guys enjoy! =D
