i think the worst time to see a show is either right after it opens or right before it closes.
over the years i have seen so many shows either on broadway itself or on tour that i am not sure i can list them all. some of the highlights were
hello dolly with carol channing
the king and I with yule brenner
the original chorus line
best little whorhouse in texas
i love my wife
le cauge a fauxe(i can never remember how to spell that show)
annie get your gun with marilou henner and another time with florence henderson
damn yankees with donny most
throughly modern millie
the lion king
beauty and the beast
showboat with forest tucker
gypsy with bernadette peters
and several that i can't remember the names of. thank heavens we have several theaters and perfomance halls in the tampa bay area and they bring in top knotch shows. I also manage to get myself to nyc every other year or so so I can spluge and see the real thing.
