(Photo by Joel Ryan/Invision/AP) (Newser) – Less than a month after the Boy Scouts declined to make a decision on its gay scout ban, some serious fallout: Train and Carly Rae Jepsen, both of whom were touted as headliners at the National Scout Jamboree in July, have bowed out of their concerts. Train did so Friday, explaining that they had not been aware of the anti-gay policies and would not participate unless the policies were changed. "Call Me Maybe" singer Jepsen joined them today, Gawker reports. She tweeted that she won't be participating because she's "an artist who believes in equality for all people."
