Abigail is a common name. Maybe the user is thinking of Abigail Breslin, but she's an actress and not associated with Toshiko. Or Abigail Breslin's movie "Little Miss Sunshine," but Toshiko didn't work on that. Alternatively, Abigail is a character in many films, but without more context, it's hard to say.
Another angle: Could "Tushy" refer to the slang term "tushy" meaning bottom, which is a nickname for someone with a notable posterior? If so, maybe the user is referencing a different person. But given that the user is asking about movie work, it's more plausible that they meant Toshiko Akiyoshi. Alternatively, maybe the user intended "Toshi" instead of "Tushy," shortening Toshiko.
Wait, perhaps the user is referring to the song "Abigail" by Toshiko Akiyoshi and her band. Let me check her discography. She had a song called "Abigail" on an album, maybe from the 70s or 80s. If that's the case, perhaps they're conflating the song with a movie. However, that song isn't tied to a film.
