There's the most popular version by the McGuire Sisters. There's a version by Johnny Cash. And then there are covers by British singer Alma Cogan and American musician Linda McCartney, among others.

But all these artists have just been given serious competition by this senior citizen who has entered the annals of online virality with his foot-tapping version of '50s hit "Sugartime".

He starts with "1, 2,3... Allah forgive me," before launching into a surprisingly good version of the song that is right up there with the other covers and could even be the best of the lot.

He ends with: "Anything wrong, uh?"

The folks on Twitter had a few things to say.

Earlier this year, 72-year-old Harsha Kumar DasGupta from West Bengal owned the internet with Bengali covers of Pink Floyd's classics.

Clearly, the list of senior-citizen singing sensations is long and illustrious. Here's 82-year-old John Hetlinger with his cover of "Bodies" by hard rock band Drowning Pool in the 2016 edition of America's Got Talent that won over the judges and went viral.

It's not just Western classics that are a popular choice for covers. And it's not always for the enjoyment of netizens.

Last year, American research scholar Christine Fair used Bollywood songs to take on an auto driver in Delhi who had refused to ply by meter. She sang a few lines of "Mujhe Neend Na Aaye" from the movie Dil, and when that didn't seem to work, segued into Anarkali's "Yeh Zindagi Usi Ki Hain". Her tactic worked and the auto driver conceded defeat and offered to take her wherever she wanted to go.
