Wreckless Eric and Amy Rigby are on Billy Sloan's show live tonight between 7 and 10pm (gmt). I think you can stream that live here. There's no listen again facility so fill your boots in real time.
The dynamic duo will also be on Tom Morton's BBC Scotland show on Tuesday (4th). That will be on the listen again feature for 7 days after that.
Tonights Wooden Shjips thing, there are no advance tickets. It's pay at the door (£7 supposedly), doors stated to open at 9pm. The Shjips will be onstage 10.30/11pm, after the stragglers from the Shellac show haul their carcasses up Sauchiehall Street.
