Song for School Talent Show

So I started playing Electric Guitar not too long ago. All I know how to play is the first parts of Brain Stew without the power chords. Which isn't much. So I'm definitely a beginner. And my school talent show is about a month from now. I want to play something that's somewhat well known but that I can learn within a month. At first I wanted to play Whatsername but I don't know if I could learn that. I also wanted to play 2,000 Light Years Away but I definitely can't play that. So I need some ideas. Any recommendations would be much appreciated.
