Joe Walsh was recently joined by Ringo Starr to perform a rendition of the former's "Rocky Mountain Way."

The Eagles member invited the Beatle, who also happens to be his brother-in-law, on stage during his concert at the Forum in Inglewood, California on Friday, May 20.

Starr is married to Barbara Bach, who is the sister of Walsh's wife, Marjorie.

"That don't happen every day," Walsh said after the two finished up the song.

Walsh is currently on the road with the One Hell of a Night co-headlining tour with Bad Company.

The tour goes on for another six weeks and will wrap up on the Carl Black Chevy Woods Amphitheatre in Nashville on July 3.

After that tour Walsh will be heading out on his own tour, which will kick off on July 16 at the PNC Pavillion in Cincinnati, Ohio and will wrap up on September 17 at the Belly Up in Aspen, Colorado.
