Tammy Boness & The Swingin' Mammaries

Tammy Boness & The Swingin' Mammaries are an oldies band featured in Grand Theft Auto 2. They have one known single: "The Diner", which is heard on Lo-Fi FM and Lithium FM, respectively listed as the third song and the second song on the radio stations. The song has a sound reminiscent of 1950s soul music.

The version of "The Diner" featured on Lithium FM has defects, such as record skipping, and stops sometime after the halfway point due to Spaz Funbags' frustration with the record, while the version on Lo-Fi FM has no such defects.

The band's name is a reference to nudity and breasts, an example of Rockstar's sexual humor.

"The Diner" was written and produced by Craig Conner and Julie Wemyss, who also composed music for another fictional band, Conor & Jay.
