Available as a bonus in Time Life box set Carol Burnett Lost Episodes
The inclusion of Lucille Ball was partly because CBS insisted on Burnett having an established co-star for the special, and also because Ball already had a contract with CBS for up to three specials (in addition to "The Lucy Show") for the 1966-67 season, of which she would only produce one, "Lucy in London."
The special was sponsored by American Motors Corporation (AMC). The first commercial in the hour-long program stars Sid Melton, who had appeared in three episodes of "The Lucy-Desi Comedy Hour." Although the AMC commercials are not included on the DVD release, some of the kinescope prints still retain the filmed commercials. The DVD does include, however, Carol Burnett's intro to two of the commercials.
The show was such a critical and ratings success that CBS rebroadcast it on January 15, 1967. It was released on DVD on May 17, 2016. In April 2016, MeTV broadcast the special for the first time in 50 years.
Lucille Ball had a rudimentary knowledge of several musical instruments, but banjo was not one of them. She was miming to a pre-recorded track. Two years later, she would once again mime playing the banjo, this time with her daughter Lucie and Wayne Newton on an episode of "Here's Lucy."
