I'll be doing "I Will Search" next...along with "Sweet Home Alabama"...there's just too many people out there incorrectly teaching the intro to that tune and I've got to put a stop to it. 
So, is it the incorrect C chord that irks you, or the incorrect "bun-dun-daw-dee-dun-daw-dee-duh" part? lol (that would be the little hammer-on/pull-off thingy as it would sound verbalized...)
I, personally am still a fan of the "bun-daw-doo-do-daw-doo-do-wahhh" lick...

I just might need medication... (j/k)
