Copies of the specially commissioned song City by the Sea are disappearing fast.

The long-awaited recording, sung by thousands of children, relives the musical sensation from earlier this month when 40,000 children completed the annual Children's Parade in Brighton.

The song was written by Mark Chadwick of The Levellers and Stephen Clark to mark the 40th anniversary of the Brighton Festival.

The children were led by Strictly Come Dancing celebrities Zoe Ball and Patsy Palmer.

The Argus recorded the performance and has produced 5,000 exclusive CDs.

To obtain a copy people need to collect three different tokens from the paper which are being printed every day this week until Friday.

The vouchers can be exchanged for a copy of the CD at Sussex Stationers in East Street, St James Street and Western Road in Brighton, George Street in Hove, Station Road in Portslade, and Southwick Square in Southwick.

The offer will continue while stocks last.
