Who are Lennon and Maisy?  They are the cute little girls from the ABC show "Nashville" that sang the Lumineers song "Hey Ho" on the show. Recently that YouTube video has become and internet sensation. Last time I checked it had over 600,000 views.

So where did they come from?  Lennon and Maisy are the children of the the Canadian duo The Stellas., who finished in fourth place on the second season of the CMT series "Can You Duet" in 2009. Their self-titled debut album was released by EMI Music Canada in September 2011. I think they are incredibly talented.  What do you think?  Are they just a novelty kid act or are they the next big thing?  You be the judge. Here are Lennon and Maisy singing Johnny Cash's "Ring of Fire" at the Ryman Auditorium in Nashville.
