The Curious Matter of RK

In my spare time, I have this rather unalterable habit of hanging out at my local mechanic. It is something like a tremendously de-glorified version of that popular series on Discovery - Orange County Choppers. The only difference here is that the people are a lot under-nourished, the tools are virtually non-existent and not much headway has been made in the areas of hygiene since the stone age. But the desire to be around cars overpowers everything else, even common sense.
So, a couple of days ago I was hanging out at the mechanic's with a friend of mine, and was shooting mental hoops. A group of solid citizens were standing close to me, talking things that only they could claim to understand. But the mildly disturbing thing was that they were gesturing in my direction for some time. Suddenly, one guy walked up to me and shook my hand and introduced himself as some kansamy. He then proceeded to ask me for a "chance". He said that he could sing very well and I just had to give him one opportunity, and that he wouldn't let me down. I said, I would love to help him out, but just didn't know anybody in the singing business. He then became aggressive, and started threatening me with things like he will start singing right there. Suddenly, another odoriferous creature that was hanging around pounced in our midst and started stuttering strange requests with atleast a zillion "saar".
As they started to form a circle around me, chanting "saar... saar.... saar", I guided the cheap plastic headed scooter key made of tin, between my fingers, and started to meditate on Bruce Lee. That was when the mechanic arrived, and shooed them away. Some ten seconds later Mr. Tenor came up to me again with extended hands and said, "Sorry saar. I thought you were RK of Sun TV. You have the same cut out. Eskoos." and left the general area.
I made it a point to google who this RK bloke was, to no avail. I tried all probable keywords like, "ghastly singer, ugly man good voice, regional hotshot" and so on, but there was not even the slightest of hits. I even queried the prolific blogger jawaman but even he was clueless.
If I am Clark Kent and people are getting suspicious, who in the name of the pluguglies of South India, is Superman?
