This just came in from Streetlight Manifesto:

we once again have to bid farewell to a longtime friend and band member. jamie egan, trumpetist extraordinaire is leaving the band to be with his family. jamie had a hard time with his decision, as he absolutely loved doing what he did on stage and he will miss you all. it came down to a hard decision for him, with a life of touring on one side and his kids and career as a teacher on the other. obviously no one can blame him for choosing family over rock. make sure to slap his ass if you see him at school or out and about. although he won't be touring with us, he'll be part of the sm family for good and don't be surprised if he pops up from time to time.

Delano Bonner will be filling the void on the band's next few tours. No word yet if he'll be a permanent new member or not.
