Guess the name of musician

I'm a mailman.

At Christmas this year, Mrs. Jankowitz met me at the door and invited me in for a great breakfast spread.

After I ate, I thanked her and she said, "There's more."

She took me to her bedroom and showed me moves I had never imagined.

I told her I had no idea she felt this way.

She said, "I don't."

I ask, "What was all this about?"

She says, "I asked the husband what to give the mailman."

He said, "Screw the mailman, breakfast was my idea."
