I got quite the chuckle out of this blog post ... not to mention the video.
I have to admit I'd never heard of Katie Perry before this. After seeing her video of the song Hot 'n Cold I can say it was a blessing. (Not having heard of her, that is.)
I'd have to agree with blogger Molly Bergen, who in her blog post "Midnight Movie: How Do You Improve Katy Perry? Cover Her With Polka!" figures that the Ukrainian ensemble Los Colorados has improved on it considerably.
Of course, I wouldn't exactly describe what they do in this video as "polka" (I suspect Molly is not exactly an afficionado of the genre) ... but I do agree that the folk instruments as well as the Ukrainian accent add a very distinctive charm. And from what I could tell, the group's front man speaks with a real Ukrainian accent, i.e., not a Russian-Ukrainian one. (If I weren't happily married, I'd be in love!)
Anyway, watch it and see what you think!
