i go for the whole experience, too, so musicals to me are just as great as opera. i like the combo of acting, dancing, and music which seems freer in musicals than opera.
i love bernstein, too, and west side story

roy rogers - is that the name of musical - anyway - i saw the one starring roy rogers and loved it. it was about his life.
kismet
as for opera:
cavilleria rusticana - intermezzo
la boheme- your tiny hand is frozen
madame butterfly - many quaint arias
carmen - flower song
i guess it all depends on the singers, too. we had a fantastic baritone singing at the mann for the 9th symphony. have to find his name. anyway - he was one of those 'drop your jaw' voices.
