Fleetwood Mac is Playing Dallas April 30

While taking my 14-year-old to school this morning, he heard a radio advertisement for Fleetwood Mac's April 30th concert in Dallas. In the background and between talking, you could hear Landslide sung by Stevie Nicks.

Pickle: Is that the chipmunks? Cuz it sounds like the chipmunks. Are the chipmunks doing a concert?
AoM: *giggling uncontrollably* Stop that. Its Stevie Nicks.
Pickle: *sensing he struck a nerve says with a smile* Well, they sound like the chipmunks. *then he bursts into his Chipmunk voice singing the line of Landslide he heard*
