Greetings forum members - most of you may remember me from the never-ending 'Last post wins' thread, to which I will in time be declared the winner

BUT... for now, I wanted to know if anyone had any good scores or knew pieces/technical exercises for students who may be clumsy enough to say break an arm, and put themselves out of playing their 'normal' repertoire for a while??? Have you ever had a student who broke an arm, fractured a wrist etc... What do you do with them, without resorting to half an hour of scales and arpeggios???
If you have any good repertoire (or better yet - links to scores) for some pieces for either just the RH, or LH - I (and I'm sure many others) would appreciate it being posted here.
PS. The easier, the better for now... Don't suggest anything like Alkan's 10 min etude for the LH. We're talking about for students - not masters.
