The Who's Roger Daltrey has unveiled the first stone on the Music Walk Of Fame in London, days before he will have an operation on his throat.
Bandmate Pete Townshend joked that the tribute should really have been in west London's Goldhawk Road, where the group are from, as they were honoured with the first stone in Camden.
The Who were presented with their award by Primal Scream's Bobby Gillespie at a ceremony in front of fans and friends including Suggs and Jazzie B.
Daltrey, who has previously been treated for a pre-cancerous condition on his throat, added:
The founding stone of the walk, which will act as a guide to the unfolding route, was unveiled by DJ and producer Jazzie B.
Using the Music Walk of Fame app, visitors will be able to scan the founding stone to be taken on a journey through the culture and history of music.
