I don't understand the word partying in this sentence
Is it comes from "are partying" or "who are partying"?
If it the present continuous, why doesn't "are" or "who are" is written before it?

John, interested in stamps,...
Here, we can skip the 'whois'.

The sentence fragment is attached to the first senetnce, defing what is "sad". If one wanted it to be a sentence one would put "are" before "partying" to make a complete progressive verb. If one inserted "who are" it would remain a sentence fragment, but it would change "partying" from a participle-adjective to part of progressive verb in a relative clause.

I don't understand please answer these questions...

1. Do you mean The sentence fragment is All these older guys partying way past their prime."??

2.Do you mean sentence fragment is a part of sentence?? so is a fragment of what sentence--- A.It's sad--- B. isn't it ?? or it is not a part of sentence??
