In this Italo Disco project, Roby was represented by model Raffaella Del Rosario and sung by Simona Zanini, and Topo was a robot. The music was actually produced and performed by Aldo Martinelli and Fabrizio Gatto, with Zanini's vocals and percussion by Franco di Trani. Other Martinelli-Gatto-Zanini collaborations included Martinelli, Doctor's Cat, and Raggio di Luna.

Set On Fire (TRD 1083) was sung by Antonella Pepe on Time Records.
