I love "Wonderful Town" - I've not worked on a production - but
have seen several amateur productions - and the terrific
Broadway production with Brooke Shields a couple of years
ago.

What I have noticed as an observer is that the singing isn't that
difficult - but the orchestration seems (to me) to be a monster -
LOL - Bernstein, you know LOL. Also, it's very energetic and
lively - which also translates (in a musical) as a LOT of dancing.
There is definitely one number that requires a male dancing
chorus, so you will need a few guys who can dance. There are
quite a few sets - but nothing that is impossible to achieve.

If you choose to do it, good luck! It's a good show that should
get more productions IMO.

Oh - I have two different recordings of it - the first with Rosalind
Russell - and the newest Broadway revival. Both are quite
good, fairly complete - and you could get a good idea of the
music from a listen-through.
