problem is I cannot think of anything off the top of my head that fits your bill
things like the Byrds 8 miles high and ELO rock aria are pinging around but they are really a homophonic texture with a great melody and bass line sandwiched around them
possibly talking heads road to nowhere opening vocal is a good example of homophony - many voice lines but in strict rhythmic and harmonic step, as is queen's somebody to love
I'll do some thinking and get back to you
two that just popped because of the queen reference is the Prophets song from night at the opera, also good company smae album
and then a few on sheer heart attack (3rd album) by queen
