They auditioned a number of singers, including Ron Reyes who was briefly the singer for Black Flag, while working on material which included the main riff to what would become "Rocket Queen" (though Adler stated in a later interview stated that no Road Crew material was used until the recording of the "Use Your Illusion" albums). Despite there being a good chemistry between the trio, Slash disbanded the group citing not being able to find a singer as well as Adler's constant partying and lack of work ethic compared to himself and McKagan.
