As a commenter on MetaFilter points out, if you’ve ever wondered what William Shatner would sound like performing one of his spoken word albums as a member of the British aristocracy, then now’s your chance. But while entertaining, the vocals aren’t the real reason you need to watch this fantastic clip, which UK ad agency RKCR/Y&R created to pay homage to Sir David Attenborough’s final appearance on the BBC. Rather, it’s the breathtaking wildlife footage pulled from the filmmaker’s vast collection, made even more poignant when paired with Louis Armstrong’s timeless lyrics. Check it out now for some instant warm fuzzies, and for more Attenborough, be sure to mark your calendars for March 12. That’s when his latest project, Frozen Planet — a seven-part series which focuses on the effects of climate change — will make its US debut on the Discovery Channel.
