Although, you know, it was a good stab at the whole street dude/urban youth thing.
The hat was there (perched high on head and pulled to its fullest extent, as below) :-
along with the clothing, the manic street lingo and the general attitude.
Which I silently endured, after the `dappy pack' hopped, on for the rest of my journey home (about four stops).
Conversation between the `dappy pack' went thus :-
Dappy (or `D' for short) : "Man, o man, this has been the longest day of my life bro."
Dappy Pack Member 1 (or `DPM1' for short) : "F*ckin' ell man, you see what that pig did?"
Dappy Pack Member 2 (or `DPM2' for short) : "I told him, I said `Put your hands behind your back, man, otherwise they'll smell 'em', and what did he do?"
D : "Bro let us down. Man, when I see him he's gonna get majorly fattered."
DPM1 : "He just turned round to that cop guy and held out his hands. I bet he's gonna start saying names nah."
DPM2 : "O man, I never thought of that. Fuck, yeh."
D : "Listen we dont know what's going down .... Hogan will know. Get Hogan."
DPM1 frantically dials on his mobile, whilst D and DPM2 hold their heads in their hands, being careful at all times not to dislodge their stretched hats.
DPM1 : "Hogan? Yeh, man, we've gone ... you heard anyfing? He what?!!!"
DPM1 starts shaking his head whilst D and DPM2 hold their urban breath.
DPM1 : "O Christ. I knew it. F*ck's sake!"
DPM1 terminates the call, rolls his eyes and chuckles slightly.
DPM1 : "He's busted us all! Hogan said they're waiting for us at the next station. Man, it's all gonna go to pepper then!!"
It's at this point I spot D sliding on a silver nuckle-duster and DPM's 1 & 2 pulling down their stretched hats and pulling up their hoods.
I guess that, at this juncture, I should have quickly stepped in to the next carriage, but I was so amazed at what I was hearing/seeing that I just sat there instead (whilst quietly blinking at the recently produced finger weaponry).
And, as the train pulled into its final stop, I watched the `dappy pack' get off - only to walk (in a quiet and subdued fashion) straight into the arms of some waiting police officers, a few station staff and (what appeared to be) some very angry looking parents.
D was the first one to cry, with DPM's 1 & 2 breaking down shortly after.
But then, I'm not surprised.
They could have only been about 10.
