 In December 2008 the band also announced that for their 30th anniversary in 2009 , they would be staging a fifth Madstock festival in London 's Victoria Park on 17 July 11 years after the last Madstock concert . It was originally rumoured that the newly reformed The Specials would make an appearance after finishing their reunion tour . However , this did not occur , although original Specials keyboardist Jerry Dammers – who was not part of the reunion line @-@ up – was announced as a support act with The Spatial AKA Orchestra shortly before the festival . Dammers would support Madness again during their 2009 Christmas tour , when he opened each night with a DJ set .
