It was produced by Paige and the tour's musical director Chris Egan.
The recording, made at Vicar Street, Dublin, features tracks from throughout her 40-year theatrical career.
The final, bonus track on the album is a studio recording, "The Things You Are to Me", written by Brendan Graham and Rolf Løvland and recorded by Paige for their Secret Garden album, Inside I'm Singing.
The album was self-financed by Paige and sold at concert venues as well as via her website.
It is available on CD in the United States through Amazon.com under the title Celebrating 40 Years On Stage on a PBS label, containing the same 18 live tracks and additional studio bonus track.
