Martin impressed delegates by opening his address in Welsh, after some intensive coaching. He particularly buttered up local members by telling them "a'u dealltwriaeth o egwyddorion yr undebau llafur yn ei gwneud hi'n bleser cael dychwelyd atoch", which we are reliably informed means their "warm hospitality is linked with their firm grasp of the principles of the trade union movement".
Plans o screen a simultaneous translation however came awry when it went missing, and the kitchens at the conference hotel had to be raided for Welsh speakers to write out a last-minute replacement.
Martin, as is traditional, brought along guests from his local authority, Lewisham - including deputy mayor and former education chair Gavin Moore, who is very, very New Labour.
The speech, attacking Tony Blair as "bourgeois" must have made uncomfortable listening and Gavin was apparently seen to sit on his hands when it came to applause.
