This week, Lawrence's quest is to be a rock star. When he was a child he was kicked out of his school band. He was a musical maverick, but now is his chance to make it happen. In setting about creating an image, Lawrence first learns some rock moves from You Am I rock god Tim Rogers, like the windmill, and making love to the audience. Next he gets himself some outfits and a photo portfolio (shot by his dad in a crummy back alley). Street cred. And no Mr Leung, once again, Lawrence is not on drugs, he's just trying to look like Pete Doherty. Lawrence crashes the MTV Awards in a DeLorean (the time-travelling car from Back to The Future). The Veronicas, Juliette Lewis, The Thorpedo, 50 Cent... and Lawrence. He's one of them! 50 Cent's bodyguard doesn't quite see it that way though. After his attempts to recruit famous musicians fail, Lawrence decides to outsource, and recruits a backing band from Mumbai via MySpace. He settles on the name The Sweatshop Boys and they start recording. Via Skype. It's new technology for the new rock order. The kids will understand it. As his song develops Lawrence gets feedback on the tune and the lyrics from Dicko (Australian Idol), American agent Terry Anzaldo, and his childhood musical hero - INXS's Kirk Pengilly. He asks Kirk to do a sax solo to make his song complete. With his song complete, Lawrence is ready to perform his new single LIVE on MTV's The Lair. Will his dreams of rock stardom be fulfilled?
