No, he was not. Michael J. Astorga and Jose Rodriguez comprised the terrific duo known as Pure Pleazure. They have a CD compilation on ASTORGA RECORDS / DMD ENTERTAINMENT, INC. called "Past & present". The CD has most of their great hits like: "When Will you come back to me", "Bring me back", "In and Out of Love", "Only you", "Hold me in the dark" and "You are the one". Isaac only had the hit "In my Heart" and I believe was from the Chicago area.
