What's going on with Maynard's Groovy Bible Tunes, from day to day...
Hmm... much to my surprise, the search function wasn't working on the Jukebox. I had fiddled with with way the song lyrics were loaded, and I hadn't realised that this affected how the search worked.
Anyway, I've fiddled again, and it works properly now - try this link:

It should take you to the search results for John 3:16...
