Concert

Hello, I directed Les Miserables: School Edition in 2015 via MTI. Our school is hoping to do a fundraising concert for our drama program, featuring songs from our last four musicals. How would I go about clearing the particular numbers with MTI? Or is it necessary to do so as we aren't using dialogue, sets, etc. (simply students singing these songs)? We would include the following songs in the concert: Master of the House Epilogue Red/Black Do You Hear the People Sing One Day More Thank you in advance for answering this question:)
