Records and management company ( E.G. Management ) over royalties allegedly owed by E.G. to himself and to other band members . During this period , Fripp met and began working with producer and online developer David Singleton , initially on a Guitar Craft tour in 1990 and subsequently on the production of two albums - the League of Crafty Guitarists ' Show of Hands and the eponymous album for the Fripp @-@ and @-@ Toyah @-@ fronted group Sunday All Over the World .
