Join Marc every Sunday from 1 'til 4pm with great music and chat for your Sunday afternoon.
This Sunday afternoon, listen in for your chance to win with Guess The Voice or try and guess the mystery year on the 3 at 3. Plus, Marc looks at the big stories in the Sunday papers, highlights this week's must visit local events and plays another listener's 'guilty pleasure' track.
Marc was born in Swansea and spent most of his childhood in Burry Port before moving to Wexford in Ireland.
Marc cut his teeth in radio on local Irish radio station South East Radio in Wexford, where he presented a variety of programmes as well as news and current affairs output.
Following a move to Bristol to study Media Production, Marc took to the airwaves again presenting traffic and travel news on stations across Wales and the west of England - including Swansea Sound and our sister station 96.4FM The Wave!
Marc joined the team at 1170mw Swansea Sound in 2003 and has been keeping listeners entertained on Sunday afternoons ever since!
