"We were telling everybody we weren't getting back together when we were in the studio actually recording. We wanted to try it on, to see how it would fit"

This quote by Nikki Sixx is referring to the process of taping a song with his band, Mötley Crüe. He is saying that despite the fact that they were telling everyone that they weren't returning together, they decided to try it out and see how it would fit. This could imply that they were uncertain of how the recording procedure would go, or that they were uncertain of how the tune would sound. It might likewise mean that they were not sure of how the fans would respond to the tune. Whatever the case, it seems that they were willing to gamble and see how it would end up. By doing this, they had the ability to produce a song that succeeded and that their fans taken pleasure in.
