Rock Away Blind Question

[Fever Dance]

Hey Ledgies- Need some advice please
I think remember reading a post that Lindsey told someone at a M&G that he will play Rock Away Blind if asked to during a show? I'm going to the Ft. Worth show Friday and I haven't been able to make it to any other shows this tour so I'm wondering if he's still been doing it and if so, are people just yelling for it in between songs? I really don't want to be obnoxious unless I have to be and I don't want to irritate him, since I'll be in the front row so any advice would be appreciated. Thanks
