The Sondheim Lyrics Chain

[scenicdesign71]

...seven different women — and they are all women, ranging from very-young to approaching-middle-age — singing seven different songs in which they mention their own hair. 

So, to recap:

• The three remaining instances (that I'm aware of) all come from different shows:  different from each other, and from the ones that have already been played.
• None is a cut song like "Bang!" or a later addition like "Our Little World" — these three songs have all been in their respective shows since their original productions (and cast albums), and remain in them to this day, so they're not too obscure.
• And, while one is from a less widely-known show, to those who have seen or heard it (it's had at least three cast albums), the song in which it appears tends to pop out as an instant highlight.
• None are hidden in chorus or counterpoint; the remaining three instances are all technically duets, but all three "my hair"s occur in clear, easy-to-hear solo lines.
• The three remaining instances are sung by women ranging in age from "very young" (probably even younger than Rapunzel, and, one could say, following a similar path) to "eyeing middle age from a cautious distance" (like a less-jaded Charlotte, perhaps).

MY BAD!  Turns out, that last-mentioned instance is actually sung by a man!

In my defense: he's actually singing from the first-person perspective of the woman with whom this duet is shared (or, more accurately, split).  It passes from her to him midway through — in fact, the topic of her hair becomes the more-or-less arbitrary "handoff point" at which the song segues from her vocal line to his, after a brief unison passage — but, dramaturgically speaking, the words remain manifestly hers all the way through, even when he's singing them alone.  By the time the specific phrase "my hair" occurs, he has taken over the vocals entirely, while she has likely exited the stage a stanza or two ago; but he's continuing to sing her thoughts (about her own hair, among other things) verbatim, as it were.

In light of all that, misidentifying the singer of that particular phrase in that particular context was an honest, if careless, mistake.  Still: if my erroneous claim that all seven instances were sung by women caused anyone to overlook this one — my apologies!

[KathyB]

This is the last "my hair" that I have found, and I too thought it was sung by Clara.

Perhaps when next we meet,
I'll be a sorry sight.
You won't know who I am.
My hair completely white,
My face
A mass of wrinkles.
What will you feel then,
My Giorgio?
Time is now our enemy...


Five down, two to go, and there's probably some convoluted way that "enemy" connects back to "my hair"

[scenicdesign71]

Circling back around, coincidentally...

Bang! The war commences.
The enemy awaits in quivering expectancy...
The poor defenses, the penetrable gates—
How terrible to be a woman!

The time is here.
The game is there.
The smell of fear
Like musk pervades the air...


It's not coincidental that this target happens to rhyme with "my hair"... Just sayin'.
Re-recapping, and then some:

• One of the remaining two "my hair"s is sung by a female character who, while younger than ITW's Rapunzel*, shares with her a somewhat similar dramatic arc (minus the tragic spiral to an early death); their hair bears a certain resemblance, too.
• The other is sung by a woman in a duet that many consider one of the highlights of a relatively seldom-produced show.  Out of all seven, this singer is the only one who's mentioning her hair as a point of seemingly uncomplicated sexual pride, with no apparent worries about age, upkeep, etc.  (Of course, this being Sondheim, things turn out not to be so simple).
• Each is from a different show, and neither is from Night Music, Into The Woods, Passion, SITPWG, or Sweeney.
• One of them rhymes "the air" with "my hair".
• And the other one, just as a heads-up, occurs at almost the very top of the song in which it appears, sharply limiting the available target words that could lead to it.

*Granted, Rapunzel's own age has been a matter of some confusion.  She seems like a sheltered late-teen or young adult.  But her brother the Baker has for many years been unaware of her existence, presumably having been too young to remember their mother's pregnancy — which would put the siblings' age gap in the lower single digits.  He and his Wife, meanwhile, are written (and usually cast) to seem no younger than, say, 30 — in which case, given the above, the Witch must be keeping Rapunzel in captivity well into adulthood.  But for present purposes, even if we assume the Baker is only in his mid-20s, his sister would still be older than the young lady we're looking for.
