Kai Bahman or -Wahman (and other variants) is a mythological figure of Greater Iranian legend and lore. The stock epithet Kai identifies Bahman as one of the Kayanian kings of Iranian oral tradition.
In the genealogy of the legendary dynasty, Bahman is the son of Esfandiyar (hence his also being referred to in Middle Persian as 'Vohuman Asfandyar'), grandson of Goshtasp, husband of [his own daughter] Komani/Homai, and father of Dara/Darab. Other details vary: Several different Arabic and Persian sources (e.g. al-Tabari and ibn al-Balkhi) assert that Bahman had five children; two sons, Dara/Darab and Sasan/Sassan, and three daughters, Komani/Homai (stock epithet: Chehrazad), Bahmandokht and Farnak.
In the Bahman-nama (composed ca. 1100 CE, not to be confused with a 15th-century hagiography of the Deccan Bahmanids) Bahman is portrayed as being asked by Rostam to marry Katayun/Kasayun, daughter of the King of Kashmir. Bahman does so, but subsequently has to flee to Egypt where he marries Homai, the daughter of the Egyptian king, with whom he has a daughter also named Homai. Other sources have Bahman marrying his own daughter Komani/Homai on account of her great beauty, and that Dara/Darab was the result of this union. In one tradition (reiterated by ibn al-Balkhi), the marriage was denied and Homai dies a spinster.
She wore glass slippers
She held her head up high
She had that sparkle at her feet
And that twinkle in her eye
She smiled at me
And I wondered why
She said I'm looking for a cowboy
To take me for a ride
And he can rope me on the prarie
And he can ride me on the plain
And I will be his Cinderalla
If he'll be my cowboy man
She said I've got a 40-gallon stetson hat
With a 38-foot brim
We could dance around the outside baby
'Til we both fall in
And you can rope me on the prarie
And you can ride me on the plain
And I will be your Cinderalla
If you'll be my cowboy man
Now I ain't never been no cowboy
But heaven knows I try
'Cause I'll be riding tall in my saddle
With that Cinderalla by my side
And I can rope her on the prarie
And I can ride her on the plain
And she will be me my Cinderalla
