Next decade, please!
1964: Well, D'Oyly Carte brought "authentic" Gilbert and Sullivan back!
1965: BAKER STREET: the model is MY FAIR LADY, but it never reached that level.
ON A CLEAR DAY: a real amalgam of great operetta moments and great musical comedy, but it's Alan Jay Lerner and to me it spells operetta (I omitted CAMELOT in 1960!)
MAN OF LA MANCHA
ANYA: Wright, Forrest, and Irra Petina. What else could it be? And I forgot KEAN in 1961!!!
1966: D'Oyly Carte was back!
WALKING HAPPY: this was an operetta looking for some direction
1967: The year HAIR shook up everything!
1968: THE HAPPY TIME: nostalgia, wonderful score, and Robert Goulet!
DARLING OF THE DAY: another MY FAIR LADY model, but a better score than that of BAKER STREET.
1969: 1776: another operetta set in the USA
DEAR WORLD
CRY FOR US ALL
PROMENADE: theatre-of-the-absurd attempts CANDIDE
1970: THE ROTHSCHILDS
1971: FOLLIES: this is such an epic show, stretching the "musical play" idiom so far, employing techniques of time and place begun in COMPANY, that I feel its musical demands are more based in operetta than musical comedy
1972: I think the theatre is reeling from the shock of rock and the political situation, and the closest thing to an operetta seems to be PIPPIN! But it's reallt a good song-and-dance musical comedy with a cynical facade.
1973: A LITTLE NIGHT MUSIC: all the waltzes of Strauss, Johann and Richard, and Ravel rolled into Stephen Sondheim.
CYRANO: not a great show, but some great music.
End of Decade!
