Tomorrow is Arbury Carnival. There doesn't appear to be any information about it on the web so I can't tell you any more than what I know, which is that the Cambridge Concert Orchestra will be playing in Arbury Community Centre (Campkin Road) from 2:30pm-3:30pm. It's not a concert as such: we're only background music in the room where tea is available. As far as I know you won't have to pay to get in (though you will probably have to pay if you want tea!).
So, come and support your local community, even if it doesn't have a webpage. :-)
