The hottest name in fall TV definitely isn’t Denise Richards, Martha Stewart, or Chris O’Donnell, but it might just be California dreamers the Mamas and the Papas (left). Seriously, yo!

Last night’s totally awesome Medium episode (yeah, I’m obsessed) ended with Patricia Arquette’s Allison Dubois (and her psychic friend from the 1960s) singing Mama Cass’ ”Dream a Little Dream of Me.” The oddly touching harmonic moment followed on the heels of her ”Make Your Own Kind of Music” popping up on the season premiere of ABC’s Lost, and a mention of the band on the premiere of The Apprentice: Martha Stewart by resident creep Jim. (He suggested the Mamas and the Papas as a possible moniker for Team Matchstick).

Meanwhile, today’s New York Daily News profiles British chart toppers the Magic Numbers, who’ve been compared to the Mamas and the Papas, and perhaps not coincidentally, are releasing their debut disc in the U.S. today.

To paraphrase one of the Mamas and the Papas’ classic lyrics, ”no one’s gettin’ phat, except Mama Cass.” What do you make of the band’s sudden omnipresence? And have you spotted any other Mama Cass references in recent weeks? Holla back!
