Yes, assuming it's the same bunch, I saw them in the early part of Saturday afternoon on Grange Road
riding eastbound (just before the junction with Dunton Road
/Southwark Park Road). Riding several abreast, doing wheelies, shouting, with a tail of cars behind them. A motorcyclist came really quite far across into the westbound carriageway (i.e. straight towards me in my car) to get around them!! Everything about their behaviour/attitude seemed aggressive and I was glad that my windows were up and doors locked.
