Marching with the Smothers Brothers

As I've noted here often, I'm a a big fan of the Smothers Brothers.  One of the very first LPs I owned was when a kidling was The Smothers Brothers at the Purple Onion ​(a San Francisco nightclub), which I think may have been their first album.  This below is a fairly early video of them on the Hootenany TV show, broadcast from Rutgers University in 1963.  The song they sing here, "Marching to Pretoria" was on that Purple Onion album, recorded two years earlier.
