Bob Geldof watched as his charity single claimed another historic moment by being broadcast on the Palace of Westminster.

Band Aid 30′s Do They Know It’s Christmas? featuring a range of the UK’s current musical talent became the first video to be played on the landmark building.

The single, which goes on sale in stores tomorrow, has been revived 30 years after it was first released to raise proceeds for the ongoing Ebola crisis in West Africa.

As the sun set Bob Geldof joined viewers along Westminster bridge to watch the message “help fight Ebola” and “buy this single” flash across the building followed by the music video.

The song has already become the year’s fastest-selling single reaching more than 312,000 downloads in its first week last month, the Official Charts Company said.
