Sisters Lennon and Maisy are only 12 and 8, but have the musical talent of a duo way beyond their years. In 2011, Erato, a female vocal trio, covered Robyn’s single, “Call Your Girlfriend,” using just their voices and a few cups. Now, the two girls have created their own rendition of the cover using empty margarine containers (butter’s less cool younger brother). Take a look. They absolutely kill it.
Rumor has it Amy Poehler has already given them a call - too bad, Ellen DeGeneres.
