Great version of a feelgood song, for a good cause (AgeUK), but even though it's far from explicitly mentioned in the song, its release by a group of public sector workers has an important message in this time of ideological austerity. I hope this goes some way to cheering people who provide our public services up at a difficult time, and to showing the government that a lot of people are very unhappy about the way they're treating some of our important services like the NHS, education, emergency services and social care.
