GLASGOW, SCOTLANDLead singer and guitarist for pop band Franz Ferdinand, Alexander Kapranos, is in critical condition today after being shot by a man identified as the bassist for rock group Gavrilo Princip. 'We ask fans to cooperate with Interpol to find the assailant, and call upon British Sea Power, Snow Patrol, and The Postal Service for help,' drummer Paul Thompson told music magazine NME Monday. 'The suspect had links to The Decemberists and The Libertines, and we are following up on all leads.' It is unclear whether the shooting was linked to The Polyphonic Spree's invasion of Belgium earlier this week.
