Barry Gibb recently made an appearance on the 'SNL' sketch talk show with Fallon, but now the two truly joined forces on 'Late Night' with a song from the Everly Brothers [WATCH]

Jimmy Fallon and Justin Timberlake have paid tribute over the years to the Bee Gees star Barry Gibb with their Saturday Night Live popular sketch "The Barry Gibb Talk Show." Not only did Fallon and Timberlake revisit the classic bit when they were recently back on SNL together again (with a special appearance from Gibb at the end), but the laste remaining Bee Gees brother made an appearance on Late Night On Jimmy Fallon last night, just weeks before Fallon transitions over to the Tonight Show.

First, Gibb shared his thoughts on the SNL skit and laughed about the concept with Fallon. Fallon admitted to completely creating the whole character trait where Gibb freaks out and loses his temper at any given moment:

And then the two joined up for a pleasantly surprising rendition of a song from the Everly Brothers, a special treat in honor of the late Phil Everly.

Later, Barry Gibb featured his signature falsetto and performed the Bee Gee's classic "You Should Be Dancing."

In 2010, the Bee Gees released Mythology, a four disc box set that highlights the brothers career from 1966-2001, to celebrate 50 years in music. Now, Barry Gibb has joined up with his eldest son, Stephen and his niece, Samantha Gibb, whose father was fellow Bee Gee Maurice Gibb, who passed away in 2003. Barry's younger brother and Maurice's twin, Robin passed away in 2012 after a year-long battle with colorectal cancer. They head out on tour in May. Check out the dates below.
