Glee: Scoop on Katey Sagal's appearance on the show from E! Online's Kristin Dos Santos

Here's some scoop on Glee from Kristin Dos Santos' Spoiler Chat for Thursday 4/11/13.

Sasha O.: We've heard all about Glee's "Shooting Star" episode. I want scoop on stuff happening after this week's show.
We told you that Katey Sagal is guest starring as Artie's mom, but did you also know that the powers that be at Glee have big plans for her next season? If Glee gets a fifth season, that is. She won't be singing in her upcoming episode, but we hear that Ryan Murphy and Co. are working on a big song for her. As for Artie's dad, no plans to see him yet. Which is a bummer, because Kevin McHale told us he's been pushing for Harry Connick Jr. to play his dad from the very beginning.
