I bet you'll start shaking a leg after pressing button for playing next video. This great song by Earth, Wind & Fire was released as a single in 1978 and reached number one on the U.S. R&B chart, number eight on the Billboard Hot 100 and number three on the UK singles chart.
Lurking the interwebs, I've found this version by Pomplamoose. It's much more sweet, slow and melodic. That's the characteristic style of irrelephant's music. Tell me what you think! BTW, Jack's grandma's got rhythm, right?
