is a song by Mark Avsec and American rock musician Donnie Iris from the latter's 1980 album Back on the Streets.

The title of the song has been referred to in the form of puns on a few of Iris's later albums—the 2009 live album Ah!

Frankford had moved back to Beaver County by the time the song came out, and always noticed many girls at her two daughters softball games also named Leah.

Alton claimed he gave a representative of MCA Records, Rodney Linnum, a demo tape of his song approximately eight months before "Ah!

[5] Iris and Avsec denied Alton's claims and, after they protested their innocence and refused to settle, the case went to a jury trial which cleared them of any infringement.

Although they won their case, Iris and Avsec lost the royalties they gained from the song in attorneys' fees, amounting to approximately $120,000.

The lawsuit inspired Avsec to embark on a career as an intellectual property attorney in the 1990s and he graduated from the Cleveland–Marshall College of Law in 1994.
