Interred at San Fernando Mission Cemetery, Mission Hills, California, USA.
Both he and Vivian Vance had nothing but contempt for each other during the run of I Love Lucy (1951), which is probably what filtered into their TV characters and made them work so beautifully. The two were given the opportunity to move into their own "Fred and Ethel" spin-off once "Lucy" had run its course in 1959. Despite his animosity towards her, Frawley saw a lucrative opportunity and was quite game, but Vance nixed the idea, having no interest in ever working with Frawley again. Vance got her own series, Guestward Ho! (1960), which failed, but went on to make sporadic appearances on Lucille Ball's sitcoms and in films throughout the 1960's. Frawley hit it big as Bub on My Three Sons (1960).
By almost all accounts, Frawley's off-screen personality was not all that much different from his on-screen one. A notorious misanthrope, with one brief failed marriage behind him and a fondness for the bottle, he lived in the same bachelor apartment for most of his years in Hollywood.
Unable to secure his first choice, Gale Gordon for the role of "Fred Mertz," Desi Arnaz agreed to consider Frawley, who heavily lobbied for the part. Desi Arnaz and Lucille Ball had invested everything they had for the pilot and were concerned about Frawley's alcoholism--- which was no secret around Hollywood--- Arnaz made it clear to him that, if he showed up drunk for work more than once, he would not only be fired from the program but blacklisted throughout the entertainment industry. Frawley, despite his lengthy film resume, was virtually unemployable by 1951--- thanks to a combination of his fondness for the bottle, and his disagreeable personality. He readily agreed to Arnaz's condition. He never showed up drunk on the set at all, and, in fact, Arnaz became one of his very few close friends. When Frawley died, Arnaz took out a full-page ad in the trade papers, consisting of Frawley's picture, edged in black, and three words: "Buenas noches, amigo!".
Despite the fact that they played husband and wife on I Love Lucy (1951), Frawley and Vivian Vance disliked each other intensely. Part of it was the real life age difference between the two (Frawley was 22 years Vance's senior), but essentially it was a clash of two driving, strong personalities. Vance and her fourth husband were dining out when they heard Frawley had died. Upon receiving the news, Vance reportedly shouted, "Champagne for everybody!".

When he died in 1966, his gross estate totaled $92,446, and his assets were on track to grow after he died. He had a residual deal for I Love Lucy (1951), which was unique to performers of the day; he was to be paid in perpetuity. His estate and heirs were paid for decades for rerun revenues.
He said he introduced the classic song "(Nothing Could Be Finer Than to Be in) Carolina in the Morning" in the Broadway Musical Revue "The Passing Show of 1922", which ran at the Winter Garden Theater in New York September 20 - December 2, 1922. As of this writing (May 2008), this has not been positively confirmed, as he is not listed in the Internet Broadway Database as being a cast member of that show.
In 1912, he was the first person to sing the classic, 'My Melancholy Baby.' He was appearing at the Mozart Cafe in Denver, Colorado. He happened to visit a pub on Curtis Street, where he knew the proprietor. Knowing Bill was looking for a new song for his act, the proprietor directed him to the pub's back room, where George Norton and Ernie Burnett were in the process of composing 'My Melancholy Baby.' He introduced the song that very night at the Mozart Cafe. In the audience that night was writer Damon Runyan, well-known for his drinking. After he introduced the song, Runyan, drunk and maudlin, called out 'Get Frawley to sing 'Melancholy Baby'!' repeatedly throughout the rest of the evening. Bill sang many encores. The comedy staple of a drunk requesting 'My Melancholy Baby' actually has a basis in fact!.
