Former Squeeze musician, Jools Holland, gave veterans a special visit while they made plaques for the Queen's Green Canopy.
The TV presenter and Royal British Legion Industries (RBLI) club patron made his guest appearance at a Aylesford sign making factory.

People at the site were making plaques for the campaign launched by Her Majesty, which encourages people to plant trees in the Jubilee year.
Some of the plaques will even be making their way to Cooling in Medway, a village where Jools lives.
He said: "To be able to mark the jubilee in some way, it's a great honour to be able to do that.
"I think it's great that we can put trees in and the sign will be there.
"Small children running around our village now will see them and then when we're all gone and they're grown up, they'll still be there.
"The trees will keep growing. So I think it's a great way of marking the occasion."
Retired veteran, Steve Hammond, joined the RBLI after suffering life changing injuries during the Falklands war in 1982.
He said: "If it wasn't for the Royal British Legion, I wouldn't be here today.
"So I thank them so much. I try and help as many veterans as we can with mental health issues and disabilities.
"It's my duty really to keep it on for the lives we lost"
So far 2,000 of the veteran made plaques have been sold, raising £250,000 for the RBLI services for injured veterans and people with disabilities.
Lisa Farmer, RBLI chief executive, said: "The Queen's green canopy initiative is a wonderful legacy to our population.
"As we plant trees today, they'll be here for 100s of years.
"We're so proud to be part of it and to have been the organisation that's produced the plaques, it means so much to us all."
Jools added: "I hadn't seen the work that they were doing here and I'm just so amazed with the signs and the amount made.
"I had no idea how much they were doing, they do all the signs for the Network Rail, the M25, signs for villages, the way they're doing it is so great. "
