This is tougher - What aspect of the tour would you want to oversee? The tech side? The roadie side? The business side? The overall administration of the tour (you'd be everybody's boss!)

I just got this email the other day and you can try this avenue - http://www.music-jobs.com

I would recommend having a degree related to the field or at least a lot of past experience in venues and booking as well as promotion - stagecraft training is going to be helpful to you as well as legal understanding. There is so much that happens to make a tour successful. If you haven't gone to college yet (and even if you have) Berklee College of Music is a great place to prepare for Music Industry jobs.

Here is Berklee's take on different elements and jobs within Business, INCLUDING Tour work

But you can work as an intern or entry level at a concert promotions company and start at the ground level and work your way up. Indicate when you interview that you are looking to move upward and explain your specific goals - stage by stage. Telling them that you are very interested in ultimately managing tours should interest them, and tell them that you are interested in being a roadie (assuming you can lift a lot and work many hours) and learning as you go.

For something amusing, you can check out these tour riders (what the artists demand on contract) for some very Pop oriented tours... you can see how detailed it gets... (THIS IS NOT the official Berklee site, but one started by a group of students)
