Hey Paul, from the amount of humor you throw around on the site here, I'd say you are a very non-serious musician - just the kind I like. Serious musicians are no fun! The quote in my profile is one of my favorite Frank Zappa bits. I've even got a T-shirt with that quote on it and I think you can still get them from the Zappa website. FZ was a guy that believed that Humor Does Belong in Music! That dovetails neatly into the Daves' questions about the Trower tune. Yeah, our guitarist pulled off the tone-thing masterfully. He still plays the '62 Strat and (I forgot the year) black-face Fender Super Reverb that a local repair shop hot-rodded with a Master volume. Beside Bridge of Sighs, we used to do Day of the Eagle, too. What a great high-energy tune that is - pedal-to-the-metal from start to finish. That particular guitar player holds a special place in my musical experience, because besides being one of the funniest people I've ever known, he's the only musician I've worked with who could play funny. I don't mean the stock little sound-bite riffs like you hear at a baseball, or hockey game, this guy can play the most inventive - and funny - stuff on guitar you ever heard. It's like having a musical stand-up comic in the band. We had this goof-off band back in the '80s in which we played our Tribute to Law Enforcement. This consisted of me playing - endlessly - the Peter Gunn bassline while the two guitarists tried outdoing each other by throwing every known TV or movie theme concerned with law enforcement, at each other. What a jam! Peter Gunn, Perry Mason, Mission Impossible, Andy Griffith, Car 54, Hawaii 5-0, Barney Miller, James Bond, etc, etc, etc. It was never boring for me 'cause I laughed so much!
BTW, Paul, I don't know if you are a Robben Ford fan, but his album Keep On Runnin' has a tune called Bonnie on it. The Bonnie in the song doesn't sound like a real nice lady. She breaks hearts, and maybe heads, as well!
Have fun, all, I've gotta go play the Peter Gunn theme and laugh a few minutes!
