Old Tiger's Head, Lee
The interior is old and run down and bizzarely includes some stuffed toy tiger heads in the corners.
There's a minimal selection of standard lagers (Carling, Fosters, Stella etc..). Apparently they do live music, but I wouldn't want to go back to find out. Go to Blackheath or Greenwich instead if you prefer a nice atmosphere for a drink.
