From Chat GPT:

found the answer! The song that played during Double Jackpot Time at Sassy Sally’s Casino in downtown Las Vegas in the 1990s was a parody of “Aba Daba Honeymoon.” It was specially written and produced for the casino’s promotion. 

The original song, “Aba Daba Honeymoon,” was featured in the 1950 film Two Weeks with Love, performed by Debbie Reynolds and Carleton Carpenter.
The marketing professional who created the Sassy Sally’s promotional version, Vince Manfredi, recalled writing and producing the parody as the musical signature for Double Jackpot Time. He also remembered hearing it blaring out onto Fremont Street. 
What about the lyrics?

Unfortunately, I couldn't locate a recording or a complete set of lyrics for the Sassy Sally’s version. It was a custom parody of the original song, so the lyrics would have been different from the standard version. I don't want to give you made-up words and pass them off as the real lyrics.
One promising lead: the original creator may be the best person to ask for a copy of the recording or the promotional lyrics. His recollection specifically confirms the song's connection to Double Jackpot Time.
