Musical Crossovers!

[phantom phan2]

What two musical crossovers [or more if you're game] would you love to see on stage?

Characters, setting, musical numbers from one show performed by a character of another etc

I'm unsure whether this was an old post if so, feel free to go wild with the myriad of new and wonderful shows we've been blessed over the past few years.

Not quite answering your question, but I've always loved that line in Me and My Girl that implies that the person who gives Sally Smith lessons in how to be a lady and basically solves the plot is none other than Henry Higgins!
