Songs for E.Africa concert gig

I am organising a benefit for the victims of the East African famine on October 19.
I'm hoping to perform new words to two songs: Leonard Bernstein's Some Other Time, and Jerry Lieber and Mike Stoller's Is That All There Is?
You can hear Tony Bennett and Bill Evans performing the Bernstein at http://youtu.be/Brooklyn.
Here's a video of Peggy Lee singing the Lieber & Stoller masterpiece:

I'm writing some new words for them both. I haven't done the words for the Lieber & Stoller, but here are my new words for the Bernstein, which I believe to be one of his finest melodies (not to mention Bill Evans' superb accompaniment, which he also turned into his Peace Piece).
For some reason, the song wasn't included in the On the Town movie (Sinatra would have done a great version) and, actually, though Bennett is one of my favourite singers, he doesn't convey the weltschmerz of the song's resignation as well as well as the Broadway cast. Did: You can hear the original Broadway cast recording HERE:
Here are my new words, which are dedicated to my friend, Rosebud:

This is the only moment,

Time to find what each high and low meant.

Go well!

There can be no other time.

There have been vows unspoken.

Now when our hearts are still unbroken

Go well!

There can be no other time.

Just when we thought we'd never

Find a way to love for ever

Suddenly we are fancy free, and now . . .

There's no more time for waiting

We've spent too much time hesitating

Go well!

There can be no other time.

Stay well!

For this is the only time.

This is not a song of parting. Go well (Hamba Khalie in Zulu) and the
response, Stay well (Sala Khalie) suggest "until we meet again".
