The clip began with a group of men standing around a huge bonfire. Are they homeless guys seeking warmth by the fire or men trying to set something on fire – a vampire, perhaps?

Then, a long-haired guy we later identified as Tim Houst began to sing…and it was heavenly!

His deep voice was the perfect beginning for the awesome song by Johnny Cash, Ring of Fire. So, that was why they were gathered round the huge bonfire! The group is called Home Free which uses only vocals to create amazing songs; both originals and covers the one in this video.

Another guy sings right after Tim but he is not from Home Free but from another acapella group called Pentatonix (PTX).

By the way, did you know that the percussion signs are made by their own beatboxer? Try to watch him in the video:

This is not the first time Avi Kaplan appeared in a Home Free video. He also had a cameo role in the group’s original music video, Champagne Taste (on a beer budget).
