The Court Yard Hounds (Emily Robison and Martie Maguire) are hosting another party tonight for fans, with a special celebrity guest also added to the festivities. The sibling duo will stream a live web chat and mini-concert tonight (April 5) on their official website, beginning at 8:30 PM ET. They've invited Grammy Award-winning singer-songwriter Shawn Colvin ('Sunny Came Home') to join in the fun, and are requesting that fans send in questions to be answered during the chat.

As proven by past CYH gab sessions, no topics are off-limits. Last month's chat with Patty Griffin found the ladies discussing Charlie Sheen's questionable behavior, while the month prior had Martie and Emily dispelling rumors that the Dixie Chicks have parted ways.

In addition to answering all of your burning questions, Shawn, Martie and Emily will treat fans to intimate, acoustic performances of each other's songs, including tracks from the Court Yard Hound's self-titled debut album.

To submit your questions for tonight's web chat, leave them in the comments section below, or shoot us a message via our Facebook or Twitter pages, and we'll pass them along to the Court Yard Hounds. You can also send in your questions by visiting the duo's official website, which is also where you'll tune in tonight to watch the live webcast.
