Continuing the Smothers Brothers kick - here, they perform "
I Love My Shirt" with the song's composer - Donovan.
According to the book
Dangerously Funny, Donovan had agreed to appear as a regular on a horoscope-themed summer series that would have run between the
Smothers Brothers Comedy Hour's third and fourth seasons. Alas, the show was canceled by CBS before the summer series or the fourth season could be produced.
