This will be followed by a reception at Sopwell House Hotel, Cottonmill Lane, St Albans.
Anyone from the industry wishing to attend the funeral and wake will be very welcome. Family have requested attendees not to wear black, as it is a celebration of Rob's life.
The family have requested no flowers but donations can be made to the Princes Trust at www.princes-trust.org.uk/robwilliams or contact Jeanette Appleton (Jeanette@dolphinmusic.co.uk) for further details.
There will also be a number of fund raising events in memory of Rob in the forthcoming future.
A website in tribute to Rob has been set up for people to post their comments and memories of Rob. The Williams family is said to be taking great comfort in reading the comments posted on this website.
