A Funny Thing Happened on the Way to the Forum

I suspect that Stratford's production of the 1950s musical is as fine as it gets.  Nevertheless, I found the musical numbers tedious. Once again, my dislike for musicals is confirmed.

Obviously, Stratford includes it (along with West Side Story, this year) because it generates large attendance numbers and thus income.  But, why, why, why, must they mic and amplify the performers?  The theater's not that large, and surely the singers have voices large enough to fill the space.  

Caveats.
