On Nov. 4 the cast of the hit TV show "Nashville" will release Christmas With Nashville, an 11-track album of holiday classics and originals recorded by stars of the show, including country music duo Lennon & Maisy. Ahead of the album's release, Lennon & Maisy participated in an exclusive GRAMMY.com interview, discussing their "cup song" cover of Robyn's GRAMMY-nominated hit "Call Your Girlfriend" and performing together as sisters.   

"We weren't even [thinking], 'Oh this is great. It's gonna go big. It's gonna do so awesome,'" said Maisy Stella regarding recording their version of "Call Your Girlfriend," which was inspired by Swedish group Erato's "cup song" version. "That's not really what we were thinking at all. Because our family is in Canada … we just wanted to show them."   

Comprising Canadian sisters Lennon (15) and Maisy Stella (10), Lennon & Maisy moved to Nashville, Tenn., in 2009 with their parents Brad and Marylynne Stella, who perform together as the country music duo the Stellas. In 2012 Lennon & Maisy were cast on the hit series "Nashville" and during the first season performed a cover of GRAMMY nominees the Lumineers' hit "Ho Hey," with their version cracking Billboard's top Digital Songs chart. That same year Lennon & Maisy released Live YouTube Sessions, a three-track EP featuring their cover of Robyn's "Call Your Girlfriend," which has garnered more than 24 million views on YouTube to date.

In 2014 Lennon & Maisy released two singles that peaked in the Top 40 on Billboard's Country Digital Songs chart — a cover of Edward Sharpe And The Magnetic Zeros' "That's What's Up" and "A Life That's Good," the latter of which is featured on The Music Of Nashville: Season 2, Vol. 1.

Produced by GRAMMY nominee Jay Demarcus of Rascal Flatts, Christmas With Nashville features 11 holiday songs from "Nashville" stars Lennon & Maisy ("Christmas Coming Home"), Clare Bowen ("Santa Baby") and Hayden Panettiere ("White Christmas"), among others.

Lennon & Maisy are currently starring in the third season of "Nashville" and are set to be featured in the forthcoming HBO special "Saving My Tomorrow," which premieres Dec. 15. The duo is also scheduled to perform at the Grand Ole Opry in Nashville on Dec. 16.
