I just listen to Before The Parade Passes By and Hello, Dolly! from following versions -
Original Broadway Cast Recording - Carol Channing, 1964
London Cast Album - Mary Martin, 1965 *
Broadway Cast Recording - Pearl Bailey, 1967
Original Motion Picture Soundtrack - Barbra Streisand, 1969
The New 1994 Cast Recording - Carol Channing, 1994
New Broadway Cast Recording - Bette Midler, 2017
Pearl Bailey's version for Before The Parade Passes By is my favorite, followed by Bette's.
Barbra's version of Hello, Dolly! is my favorite, followed by Carol Channing's 1994 version.
Barbra sings it so smooth, I can never quite understand how she makes it work so well. There's affection, but great amount of sexual tension in her take of the song which makes me feel positively drunk.
* - My album's dated 1964, even though the show opened in London in 1965, not sure what's up with this.
