Why did Jason lancaster leave mayday parade?

Jason Lancaster was facing the death of his father, and his ideals about settling down with his new wife Katie. (Yes, Miserable At Best's Katie) [They are now divorced]

He wasn't ready to push the new album, or tour either. Although Jason was an amazing part of Mayday Parade, he has gone on to create his own music and band, Go Radio. Mayday Parade has also grown and developed without him. As a good fan, supporting both bands is an important aspect of their continued strides in the music industry.

Although there is some controversy about being second vocals, and second string to Derek Sanders, It was widely known that the members were extremely close, and the loss of Jason Lancaster was devastating for all those involved, including the fans who miss the beautiful music they created together.
