Collaboration was done on the songs "Take Everything," "My Fight (For You)," and "Come Clean." Michaelson's bandmate, Allie Moss released a 2009 EP entitled "Passerby". A single from the EP, "Corner," was picked up in the United Kingdom by British Telecommunications for their BT Infinity television commercials. Other past and present band members include Chris Kuffner (bass), Bess Rogers (guitar), Saul Simon MacWilliams (keys), Billy Libby (guitar), Sarab Singh (drums) and Elliot Jacobson (drums). In 2010, Michaelson co-wrote a song entitled "Parachute" with Marshall Altman which was covered by British singer Cheryl Cole on her debut solo album "3 Words"; it peaked at number five on the UK Singles Chart in the United Kingdom. She initially felt the track was "so poppy" that she could not release it herself. However, after the song was reworked by "Everybody" producer Dan Romer to make a more "interesting, funky production," Michaelson released the song as a personal single. There are two different music videos for the song. Of the release of "Parachute" and upcoming material, Michaelson explained in a 2010 interview with Billboard.com, "I just felt like I wanted to put something out. I'm not ready to put a full album out, so we thought we'd put this out and see how people take it or don't take it." She said that she expects to release her next album, "probably in the middle of next year." In 2012, Michaelson and Laswell co-wrote and sang the duet "Landline", which appeared on his album of the same name. Her 2014 album, "Lights Out", was very much a collaborative effort. "On all my previous records, I’d written all the songs myself. It was one producer and me locked in a room for months," she said. "Not that that was bad, but I think that everything has a season. I never wanted to kind of give up control. I think I’m letting go of a lot of things – embracing the idea of allowing people to help me in all facets of my life. I think that I was a bit of a control freak, and I’m just more open to letting people be part of things that they weren’t part of before. It’s really liberating. I had the best time ever on the last record.
