The English are sometimes quite funny. In the two youtube videos we see father and son, both are born entertainers. So why not showing off your skills on youtube? But what are neighbors and friends think of one, when they see the vocal performance? The risks are great, the one that makes himself a laughing stock. So the two have summarily bought a realistic latex mask for their performances. The artistic performance is quite well done, the mask was not necessarily appropriate. Fuck what the neighbors think, the main thing you had your fun. Put the latex mask off!
