McLachlan, Indigo Girls Turn Up On "Ellen," Pay-Per-View

November 25 [9:00 EDT] -- Sarah McLachlan and the Indigo Girls are the latest folks to hop on the "Ellen" guest star bandwagon, as the musicians will tape an episode of the show next month.

McLachlan and her Lilith Fair counterparts the Indigo Girls will film shoot their appearance on December 4 and 5. There's no word yet on when the episode will air, but the plot will apparently involve series star Ellen DeGeneres attending a concert featuring McLachlan and the Indigo Girls.

Those two artists will turn up on TV much sooner than that when a special chronicling this summer's Lilith Fair tour comes to pay-per-view this Friday.

Both of those acts will also join Sheryl Crow and Missy Elliot on December 16 in West Palm Beach, Florida for a Lilith '98 preview concert.
