Christian singer Paul Janeway recently revealed he was stunned that his song appeared in the polarizing 'Fifty Shades of Grey' film. However, he admitted he was not familiar with the popular book series' sexual themes when he originally agreed that his song would be featured in the movie.

Janeway is best known as the front man of the soul band from Birmingham, Alabama, the St. Paul & the Broken Bones.

"All right, my first Fifty Shades of Grey question! When they presented the licensing opportunity, they presented it as: It's going to be a huge movie, they want to put a decent amount of the song in the movie in a nonsexual scene," said Janeway in an interview with the Mother Jones website.

"I knew it was a book, but I had no idea what it was. So I was like, sure, big movie, good exposure. I'll be in this romantic comedy. Which is what I thought it was: a romantic comedy. It's a good way to make money in the music business, you know. Then I saw a preview for it, and I was like, "Oh, s**t. Oh, no. What have I done?"

Janeway also shared how relieved he was that his song "Call Me" did not appear in any sex scenes in the film debuted in movie theaters on February 13, 2015.

"To me it's kind of funny. I'm glad it's in a nonsexual scene to be honest with you, not for my sake but for my family's sake. I don't have any moral things about it. It's not like we're in the movie-it's just a song for a minute," said Janeway.

The passionate singer talked about his soulful band's diverse themes that are featured in their recent album 'Half the City'.

"I got married seven weeks ago. It's weird because I'm very happy, and some of the songs are about heartbreak. I'm not really heartbroken. When it's show time, when you have a song that's danceable, it's easy to sing about love and sex," said Janeway.

"It's really the ones about heartbreak and sadness that are difficult to handle because I have to get to a place mentally during the song that's not really where I want to be. We have this song called Broken Bones and Pocket Change. Sometimes I get really emotional, and I have to take a break, 20 seconds to be like, 'Okay, we're done with that one.' You want the song to have the same meaning it had when you sang it the first time."

Prior to his music career, Janeway wanted be a Pentecostal preacher until he was 18-years-old when he began singing at his church.
