Who is the lead guitarist for Richard Marx?

Richard Marx, like many solo musicians, is fond of hiring studio and touring musicians. As such, I haven't been able find any mention of him using a steady band. I have, however, found out that he has employed at least two studio drummers: Gregg Bissonette and Tim Chewning. I'm almost positive that he has employed other drummers in the past, but these two seem to be the most recent. Check the URLs below for more information.

The update to that is - Tim C. had done most of the touring up until the summer of 2007. Then, Chuck Tilley took over the touring duties and has been working with Richard ever since. He also has done some recording with Richard as well. Except for a few dates, Chuck has done all the live shows since '07, including the international dates . I've seen the photos on his myspace and fb pages. Chuck is also a member of the band Sixwire, which is where I became familiar with his playing.
