Stephen Foster?

Oh, no no no--it's Cole Porter, I'll bet. The horse polo accident.

Irving Berlin

Landmark’s got it! Cole Porter. Some of his most famous musicals are: Kiss Me Kate, Anything Goes, Can-Can and Silk Stockings.

His many hit songs include: Night and Day, Begin the Beguine, I Get a Kick Out of You, I've Got You Under My Skin, My Heart Belongs to Daddy, and You're the Top.

He also composed scores for films, including Born to Dance which featured the song You'd Be So Easy to Love; Rosalie which featured In the Still of the Night; and High Society which included True Love and Les Girls.

My remaining clues would have been:

7. During college, I became well acquainted with New York City's vibrant nightlife.
8. The French Foreign Legion lists me as one of its soldiers who served in World War One.
9. I maintained a luxury apartment in Paris, where I held extravagant and scandalous parties.
10. I am one of the major songwriters for the Broadway musical stage.
11. Fred Astaire and Ginger Rogers danced to many of my tunes.

12. Tom Lehrer imagined a verse of Clementine as if it had been written by me:

Who’s Tom Lehrer? (Had to google him to find out).

Tom Lehrer is an hysterical math professor who writes and sing satirical songs while playing the piano. When I taught Chemistry, I used to give extra credit to any student who could sing his version of "The element song." I think it is the only song he did for which he borrowed the tune. Usually he writes his own.

I'll pass to whoever wants to go.

1. I was born in upstate New York
2. I served my country by enlisting in the U.S. Airforce
3. Though not related to air travel, I honed my career path while in the Airforce

4. You can't tell by looking at me, but I am part Native American

Elizabeth Warren

No, not her.

5. I have been married three times, but only to two different women. After divorcing my second wife, I remarried her when I found the Lord.

Burt Reynolds?

No, not Burt.

6. Alcoholism runs in my family and I too suffer from an addiction to the bottle.

7. I met my first wife while working as an usher at Radio City Music Hall. We had four children together before we divorced.

8. I totally changed my name when I started acting. This was wise as had I kept my original name, three of my screen roles, including my most important, would have made my name a groaner of a pun.

9. I have been in three major TV series. On the first one,I was a background character who appeared in pretty much every episode. People thought I was happy, but I left the show after two seasons to go into rehab for booze.

Kelsey Grammer

Nice try Mr. Salk, but no not him.

10. In my third and most successful series on TV, I once managed to work my alcoholism/recovery into my charcter, making him an alcoholic too.

Ted Danson?

No, not Ted, but another good guess.

11. In my successful starring role, I did not play a king, but I did have a princess I could command.
