According to this BBC article,
The Daily Mail suggested in 2016 that the song could “bring in as much as £400,000 a year.”
Asked in 2008 by the BBC whether the song had provided him with his pension, Finer said: “I don’t know because I’m not of pensionable age. I’ll let you know when I’ve got my bus pass.”
Not exactly topical news, but then the real topical news is too depressing :o)
