and Nick Lowe
fans, check this out: On October 1, the first night of Hardly Strictly Bluegrass' 10th anniversary festival
, Costello and Lowe are playing a special benefit concert at Great American Music Hall
in which they'll perform -- and, the promoters say, "bash" -- each others' songs. Lowe, of course, produced Costello's first five albums, and wrote "(What's So Funny 'Bout) Peace, Love, and Understanding," one of Costello's signature songs.
