Guitar player for blues or rock

I'm a guitar player (mature... sort of). Looking for musicians to jam with or playing covers. I'm not a professional, just passionate. I'm more into blues and 70's rock. So If you are professional, this is not for you. If you are based in London and seeking someone to play with, forming a band and work more seriously, or just have fun jamming, I'm interested. I'm quite open to any ideas. Could also play bass if necessary.
