Buddy you’re an old man poor man
Pleading with your eyes gonna make you some peace some day
The boy Queen was referring to in the beginning has now grown old, and has done nothing with life, he has wasted his time and now he has no money left to spend.
The grown up man now pleads with his eyes, which means that the only way he can make some money is by begging in the streets, but since he is old, he will not last much longer out there.
