Dance

I have been thinking of joining a dance group for some time but I haven't found any that I have been able to attend. The problem that I have is that on Tuesday I work a late shift, Wednesday and Friday I go strait from work to lessens. When ever I look for any, I find that they get to gather and train on days that I am doing something that day. I am looking for street dance classes around London on Monday or during the weekend. I don't even mind if it is underground or not advertised. I just really want to get into this. It is something that I have always wanted to do.
