The Smithsonian Channel may not be the first place music fans think of when considering “music on TV’’ options. But between programming on undersea edens and classic court cases, the cable network has programmed some engrossing and offbeat musical fare on everything from free jazz to traveling blues.

Sunday night at 8, both Beatlemaniacs and the modestly pop-culture-curious will want to tune in to the latest installment of the channel’s “Inside the Music’’ series. “All You Need Is Klaus’’ tells the quirky tale of Beatles-adjacent artist-musician Klaus Voormann. A stellar cast of talking heads, including Paul McCartney and Ringo Starr, discuss this muse, friend, and sometime roommate to the Fab Four who would intersect with the group from their early days in Hamburg to their post-break-up musical adventures.

At the peak of the group’s fame Voormann, among other things, won a Grammy for designing the iconic cover art for the “Revolver’’ album and became a member of John Lennon’s Plastic Ono Band. The classical guitarist and commercial artist went on to become a member of Manfred Mann and eventually an in-demand session player for many years.

His relationships were such that when he finally released a solo album last year — “A Sideman’s Journey’’ — he scored contributions from McCartney, Starr, Van Dyke Parks, and Joe Walsh among many others. And after checking out “Klaus”, rock fans may want to stick around for the encore presentation of “Electrified: The Guitar Revolution.’’
