As a wedding present to a friend I've promises to pay for a band to perform in the evening.

Will need to be free 6th June and have a pretty decent catalog of new and older stuff, would be good if they play live frequently so I can get too see them.

Depends on what type of music will be appropriate for your mates wedding.It may be worthwhile checking out North West Bands, sorry for whatever reason I can`t put a link to the site.
Best band I`ve seen the pub recently are Doug Perkins And The Spectaculars, rock n roll band .They do Elvis etc plus their take on current stuff , Artic Monkeys spring to mind. Their on you tube so you can have a look if thats something you might be interested in .

Chears for that.

I'm liking that rock a billy outfit and I'll have too have a look at them, the happy couple are dead easy too cater for, she likes rock on a Bon Jovi tilt and he likes geography teacher music like Mumford and Sons.

Are the Grumbleweeds still going?
