I just saw there was an album released digitally on November 20, 2020 called
America Salutes You Presents: Guitar Legends 4 which features Billy Gibbons & Mike Love dueting on “409.” It samples the original Beach Boys recording at the beginning and then cuts into the new recording. From some cursory googling, it looks like
America Salutes You Presents: Guitar Legends 4 is some sort of fundraising special, so perhaps there is a video component to this out there if anyone is able to track it down.
