L.A. singer-songwriter Tobias Jesso Jr. made his late-night television debut last night with an appearance on Jimmy Fallon. He performed “How Could You Babe” with a little bit of help from the Roots and some backup singers, who help to put a fuller spin on the Goon track. “I heard this song on the internet or something, and it just blew my mind,” Fallon said in his introduction. “This is one of the coolest songs and the coolest voices and the newest sounds. I just love it so much.” Watch below.
