I am going to download one of the snare solos from the “Let It Rip” series. I am using it for Solo and Ensemble this year. They (the Solo and Ensemble people) do, how ever, have a strict “no copies” rule, basically saying that if you have copies of the music, you can’t be judged. So, you have to buy the book or have a cover or something like that showing that you actually bought the solo. So how can I prove that I bought this solo when I hand them the solo that I have to print out? Is there something you can give me saying that it’s authentic?
