Brain teaser

A friend recently had me read this thing she did in class and wondered what my answer was. Apparently I answered correctly but I'll let you try:

In this world all married men lie and all single men tell the truth.
A young woman in a club approaches three guys.
She asks the first guy if he is married but doesn't hear his answer because the music is too loud.
The second guy replies "the first guy said "I'm married", but he is really single."
The third guy says that the second guy is single.

Determine the marital status of each man.

PM me your answer or leave a comment.
