One of my old favorite songs...
The redneck version was amusing to listen to because you got the accent down at parts... actually I don't mind it and prefer the second more than the former... maybe because you were having more fun with it.
Did you mention what microphone you were given?
For the first part, you hit most of the pitches but the intonation is a bit awkward. But overall it's alright...certainly better than what I could have been able to reproduce with my voice
