Re: I'm a little bit country, and I'm a little bit rock 'n' roll
Donny and Marie Osmond were a brother-and-sister team who had a tv show in the 70s. They sang this song together - She sang the "I'm a little bit country" to show that her musical (and my implication, her personal tastes) ran to the more country-and-western aspects of music and a simple life, while he sang "and I"m a little bit rock-and-rock" to show that he was more hip, and favored modern music.
I'm sure the wonders of youtube will show you the two of them singing. You may even get a glimpse of his famous purple socks. You will surely get a glimpse of their famous big white teeth.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
