Griff Rhys Jones has said that using his Freedom Pass is his greatest joy these days.
The 69-year-old, who has been eligible for the pass since turning 60, has recently been taking advantage of being able to travel around the capital without having to fork out a penny.
"I spend my whole time jumping on and off London buses," said the actor and comedian.
"When Mel [Smith] and I were in our pomp in the Eighties there were taxis rolling up to carry us everywhere.
"And now I’m the sort of person who says: ‘No, please don’t send a car. It’s alright. I’ll come by bus.’”
When he is not hopping onto buses, the Not The Nine O’Clock News presenter has been focused on train stations.
The relaunched Liverpool Street Station Campaign (LISSCA) wants the "insensitive and harmful" plans led by the developers of The Shard, that include the removal of the Eighties roof and original station entrance, to be scrapped.
The development plans are estimated to cost £1.5 billion and will involve the construction of a 10-storey hotel and office block.
Rhys Jones told BBC London: "It’s not necessary to say the only way to deal with the station is to completely and utterly obliterate what you see of it from the outside and inside.
"This is setting a terrible precedent, and it’s wholly unacceptable."
LISSCA previously stopped the station’s total demolition in the Seventies, and hopes to save the Grade II listed building again.
Rhys Jones and his fellow activists are concerned the new development will destroy the impression of a cohesive Victorian space and shut off the former Great Eastern Hotel from the public by turning it into office space.
