He says he is as shocked as anyone that his YouTube clip I Like Guns has been viewed more than 1.26 million times in the six weeks it has been online.

The paean to guns, produced by Bill Chambers – father of Kasey – features Lee shooting at everything from watermelons to cars, and with everything from muzzleloaders to a fully automatic M60 and a rocket-propelled grenade.

Some of the guns are so dangerous that they are banned in Australia, meaning Mr Lee had to travel to Cambodia to film much of the clip.

Mr Lee, who usually performs with his wife and four children, was inspired to write the song many years ago because of negative media coverage of guns.

"When you watch movies firearms are portrayed as a bad thing … I wanted to show that they can be used for fun and sport and not violence.''

He had never posted a song online before and did not know just how popular his song would be.
