Where the first two Grin albums had featured the band as trio augmented by overdubs, singalong choirs or even orchestras, the recent addition of Nils' brother Tom as second guitarist made the band a solid quartet.

The only additional performer is blues-shouter Kathi McDonald, who contributes backing vocals on several songs [most notably "Heart on Fire" and "She Ain't Right"].

Nils' liner notes in The Very Best of Grin attribute the "classy" solo in "Sad Letter" to Tom.

"She Ain't Right" is also notable as the only Grin tune not attributed to Nils alone, but co-written with bassist Bob Gordon.
