WATCH: 'Santa Claus Is Rockin'' for Barnardos

'Tis the season to release charity singles and brothers Glen and Simon Shire (who hail from Lisnagry, Co Limerick) have just unveiled their sterling contribution. Aiming to raise funds for Barnardos – who concern themselves with the well-being of children – Glen penned the number and Simon acted as executive producer in Dublin's Windmill Lane studios.

Thanks to their Windmill connections, the pair enlisted an elite group of musicians and producers for the project, including people who have worked with everyone from Imelda May and The Corrs to Jerry Lee Lewis and Van Morrison.

The high quality craft is clear for all to hear on 'Santa Claus Is Rockin'', with New Yorker Bradley Gillis on vocals.

Listen and watch below, then head to here to buy and contribute to the extremely worth Barnardos cause.
