original Wanting Things from the musical Promises Promises

[hereiam]

I've met someone on YOUTUBE who likes Bacharach's music
and he asked me for something from Promises Promises

I've made a video (for those who likes hiking and water streams ...
etc , they should love it) with the song though i prefer Dionne's
version

Here is the vid.

"Fly while you still have your wings ....
knowing when to leave maybe ..."

So i also made a video with the version of
Knowing When to Leave from the musical
and it's most appropriate to use the video
clips of the migrated birds from a French movie

[Steve Schenck]

Who is singing on this clip? And from what album? To be honest, I prefer Jill O'Hara from the "Promises, Promises" soundtrack; I think her performance and the arrangement are far superior to the singer and arrangement on the clip... but I DO appreciate it being posted here. I always like to hear another Burt interpretation and performance. Thanks all!
