Two listeners went head-to-head for our Lucky 13 contest for the chance to win two tickets to Robbie Williams live at Luxexpo Open Air.

The concept is simple: two listeners call into the show and try to outbid each other to see who could take the least amount of time to correctly identify a song. We started at 15 seconds, and things only spiraled from there.

Will Julia recognise the tune in 5 seconds? Will Kara get a chance to nab those tickets? Does Robbie Williams dye his hair?? You'll get the answer to at least two of these questions in this segment, which aired on a not-so-unlucky Friday the 13th.
