I like Marcus and have previously posted that he needs to steer himself into dance music, because he is quite boppy and catches the groove of a song. To do so would defuse his sexuality too - it isn't as crucial in dance music to be "available" to bedroom wall fantasists.
I thought the first week, though a tough song for him, suited him best. I'd like to see him style himself on Jamiroquai, not some retro artist, however commercial Bruno Mars may currently be. Both last week and this reminded me of something I could see at Butlins.
