I actually remembered it from a screenshot posted somewhere years ago. 
Was that black dude next to you a friend of yours ? I remember when I watched it for the first time 30+ years ago I noticed how big his arms were which is difficult when wearing a tracksuit top. Looks like he was a bit of a monster. Bigger than Joey who was being cheered on by his overexcited girlfriend.
Yeah he was my training partner...a kid a grew up with.
225 pound cheat curls,485 squat,80 pound flyes,etc. etc. and he was just 17-18 years old .....had 30 inch quads.
Talked to him on the phone just yesterday.....he`s a fatso now though.
