I linked this in another comment reply, so it's possible you've already spotted it, but a subtitled Japanese stage performance of the tennis song is actually available to watch on Tumblr, if you're curious! (The lyrics are very different from the original English version, and very homoerotic.)

As far as I know, Jordan hasn't technically played Light on stage; he just sang on the original concept album for the musical. Weirdly, although the songs were originally written in English, there hasn't actually been a full English-language performance! But they've just had a couple of concerts of the music here in London, which I'm hoping might mean they're testing the waters for a full stage production.

(And I'm delighted that you enjoyed the Tangled song!)
