The secondary display API would only work if you can output the display of one Android tablet to another. I do not believe this is supported, as android tablets don't typically have input ports for video sources. Correct me if I'm wrong.
This problem could be solved using Wifi. Other apps on the iPad have managed to implement features where one tablet controls other tablets, so that one person can turn pages for everyone. This is a feature I planned on implementing myself at some point, but there are just a lot of other things that need to be finished first. In order to support what you are describing, it's basically the same idea (one tablet controlling another), but instead of displaying the same page, it just has a page offset of 1. If I add this "page offset" concept, you could use any number of tablets, each with a different offset to display a different page in the song. The file that is used by the first tablet would need to be sent to all the tablets first, so that the only wifi data that needs to be sent is commands (turn page, etc). I do not think it would work well if image data had to be streamed.
