If, for some reason, you've yet to sense that twinkling Christmas spirit, there's no better way to get that fuzzy feeling than listening so a choir singing their collective hearts out. Mary Kennedy presents a programme of carols from the newly restored St Patrick's Cathedral, Dublin, featuring St Patrick's Cathedral Choir, the RTE Concert Orchestra, Altan, Declan O'Rourke, Duke Special and Fionnuala Gill. There's more musical goodness (if you're an ABBA fan, that is) in the form of ABBA na 20 is Fearr, at 8.00pm on TG4. It's a collection of the band's greatest hits, as chosen by Stephen Gately, Lulu, Donny Osmond and Bono.
