After Cassidy's death, local folk singer Grace Griffith introduced the Blues Alley recording to Bill Straw from her label, Blix Street Records. Straw approached the Cassidy family to put together a new album. In 1998, a compilation of tracks from Cassidy's three released recordings was assembled into the CD "Songbird". This CD lingered in relative obscurity for two years until being given airplay by Terry Wogan on his wide-reaching BBC Radio 2 show "Wake Up to Wogan", following recommendation by his producer Paul Walters. The album sold more than 100,000 copies in the following months. "The New York Times" spoke of her "silken soprano voice with a wide and seemingly effortless range, unerring pitch and a gift for phrasing that at times was heart-stoppingly eloquent."
