Hello PHIL . . .
WOW . . . you have some fine tuned ears. I think what your hearing is the mandolin riff. I hear it also and your probably correct about it being out of tune or maybe its just my playing.

I'm thinking about going back and seeing what the song sounds like without the capella breaks. THANK YOU very much for the props and comments/help.
Hey SHAD . . . A three really song . . . cool!

I appreciate you giving both versions a listen. THANK YOU for the ears.
Hey JOHN . . .
I know this is probably not your norm listen but to get the head bobbing is a huge prop in my book. THANKS MUCH for the support.
Hello MARK . . .
I'm glad you enjoyed it. THANK YOU very much for the kind words and props.
THANKS AGAIN!
Kev
