Elton John
 

Listening to tiny dancer right now, whats it about?

well considering it's Elton John 'tiny dancer' is most likely a metaphor for a cock being rammed up his keester by an anonymous stranger. that's my best guess.

The lyrics were written by Bernie Taupin, John's writing partner. They were inspired by Taupin's first trip to America. John and Taupin are from England, and this was the first album they wrote after spending time in the US.
The "Blue jean baby, L.A. Lady, seamstress for the band" is Maxine Feibelmann, Bernie Taupin's girlfriend. She traveled with the band on their early tours, often sewing together the costumes and fixing their clothes. She and Taupin married in 1971.
