This Saturday, It could be Mark sitting in for Kez as she has a gig, but the topic will be all about those songs that have appeared in adverts. It could be songs that were put into adverts years after they were released or those the were adverts then turned into songs.

Send your suggestions to Mark@ultimateradio.co.uk <mailto:Mark@ultimateradio.co.uk> or @MarkFOnAir and join Mark or Kez live on Saturday at 5 PM (BST)
