From the Super Mario Wiki
Ashley's Theme (known as Ashley's Song in the Super Smash Bros. series) is Ashley's theme song that debuted in WarioWare: Touched! The theme was composed by Masaru Tajima. The lyrics of this song are as shown below.
A less compressed version of the original theme (both English and Japanese versions) played at the original tempo is a record in the Toy Room. The game also introduces a new instrumental arrangement, used in the Pumpkin Panic minigame.
Super Smash Bros. series
Super Smash Bros. Brawl
Super Smash Bros. Brawl includes two arrangements of Ashley's Theme with English and Japanese lyrics, which play on the WarioWare, Inc. stage. These versions are performed in an upbeat, jazzy style, although there are a couple lyrical differences between the English version and the original song. Both versions were arranged by Tomoko Sasaki, with Ashley's vocals provided by Emily McIntosh and chorus vocals by Terry Lauber and James Cowan in the English version, and Ashley's vocals provided by Tomoko Sasaki and chorus vocals by the Small Circle of Friends in the Japanese version. The English and Japanese arrangements reappear in the Western and Japanese versions of Super Smash Bros. for Nintendo 3DS, respectively, on the same stage as an alternate song, while both arrangements reappear in all versions of Super Smash Bros. for Wii U on the Gamer stage and in Super Smash Bros. Ultimate in both Wario stages.
Super Smash Bros. for Wii U
The Japanese version of Super Smash Bros. for Wii U adds a brand new Japanese arrangement. The music is closer to the original theme, but the chorus has women in it, and Ashley is portrayed by someone older. This version was arranged by Keiichi Okabe, with Ashley's vocals provided by Nami Nakagawa. The arrangement was later featured in all versions of Super Smash Bros. Ultimate.
Band Brothers series
The Japanese version of Ashley's Theme is part of the track list of Daigasso! Band Brothers and it was made available as free downloadable content for the Japanese version of Jam with the Band. A downloadable PDF partition of Ashley's Theme was also released to promote the release of the original Daigasso! Band Brothers. A music video for Ashley's Theme was released for Daigasso! Band Brothers P on July 31, 2015.
There were some issues over Ashley's English theme. If the record is spun fast enough in the Turntable souvenir during the first solo, it would supposedly come out with the words "I have granted kids to Hell!" However, Nintendo and Nintendo Power both stated that it was an accident and the words come out like that due to it meshing pieces of the song together. The real words are as the following:
These words form a sentence like "Eye of grand this kitt soo pan", which is misheard as "I have granted kids to hell."
