The multi-million dollar question in the media world is: Who will get David Letterman’s time slot when the host steps down in 2015? An opening for a late night host also creates an opening for a band. Band leaders of successful shows are well-paid, and the increased exposure they get can open doors.

“It can enhance your chances of being successful at whatever it is that you want to do, simply because a lot of people know who you are,” says Jay Leno’s longtime band leader, Kevin Eubanks.

And for the musicians behind the band leaders, a regular spot in a late night band can be a nice change of pace from a hectic tour schedule.
