The Tank Bangers have posted an underwater video of their charity song on YouTube. The group is all dive guides and instructors working in the Egyptian Red Sea, and due to the downturn in tourism in the region, found that they has plenty of time on their hands. The resulting video and song is :

“At the finish line. 10 months in the making. 7 minutes long. It has taken hundred of dives and thousands of takes. It has cost us a small fortune and most of our sanity. But it is done. We hope you enjoy it. We hope you get behind us. There is much yet to do. Please share it and please buy it. Sing it far and wide. This is our chance to sing for our oceans.”

The song is available to buy and download for $3.15 (£2). All proceeds from the sale will go to marine charities.
