You got me on that one, Desert Dancer. I searched for "until it's time," and I was surprised that it didn't come up. Anyhow, looks like it would be good to tag this one for DTStudy indexing. The version I got from Buffy Ste. Marie's site shouuld be correct, and we have a few places where there are "words that tear and strain to rhyme." Here's the DT version. Note that the tune is missing in the DT.
The DT lyrics have a few discrepancies from what I hear on an early recording from Buffy Ste. Marie, so I'll post a corrected version below. Corrections are in bold

YOU'RE NOT A DREAM (UNTIL IT'S TIME FOR YOU TO GO)(DT Lyrics) (Buffy Ste. Marie) You're not a dream, you're not an angel, you're a man I'm not a queen, I'm a woman, take my hand We'll make a place in this life that we've planned And here we'll stay, until it's time for you to go Yes, we're different, we're worlds apart, we're not the same We laughed and played, from the start, as in a game You could have stayed outside my heart, but in you came Here you'll stay until it's time for you to go Don't ask how of me, don't ask why Don't ask forever Love me, love me now This love of mine, it has no beginning, it has no end I was an oak, now I'm a willow, now I can bend And though I'll never, in my life, see you again Her I'll stay until it's time for you to go

UNTIL IT'S TIME FOR YOU TO GO (corrected) (Buffy Ste. Marie) You're not a dream, you're not an angel, you're a man I'm not a queen, I'm a woman, take my hand We'll make a space in the lives that we planned And here we'll stay, until it's time for you to go Yes, we're different, [we're] worlds apart, we're not the same We laughed and played at the start, like in a game You could've stayed outside my heart, but in you came And here you'll stay until it's time for you to go Don't ask why. Don't ask how. Don't ask forever. Love me [love me] now This love of mine had no beginning, it has no end I was an oak, now I'm a willow, now I can bend And though I'll never, in my life, see you again Still I'll stay until it's time for you to go

The recording repeats the chorus and the first verse somewhat differently:

Don’t ask why of me, don’t ask how of me
Don’t ask forever of me:
Love me; love me now.

You’re not a dream, you’re not an angel, you’re a man
I’m not a queen, I’m a woman, take my hand
We’ll make a space in the lives that we planned
And here we’ll stay until it’s time for you to go.

I think the above is Buffy's original Vanguard recording. The sound quality is not very good, which may be why she re-recorded the song in recent years:
