The annual Festival Interceltique takes place this weekend in Lorient, on the west coast of Brittany. Celtic acts from around the world will perform at the event, now in its 37th edition. This year the theme is Scotland, so there's a Highland flavour to the 2007 festival.

The Irish contingent at this year's festival includes Sharon Shannon, The Dubliners (or what's left of them), Donegal fiddle-player Theresa Kavanagh, folk group Coscan, a punk-folk outfit called the Mahones (hmm, wonder which two bands inspired that name?), The Colman Irish Dancers and the New Ross Pipe Band. There will no doubt be plenty of tributes to the mighty Tommy Makem, who passed away earlier this week.

We did a double-take, however, when we thought we saw a certain Californian funk-rock band on the bill - but in fact it was just the Red Hot Chili Pipers, a gang of Glaswegian pipers who are sure to win Best Band Name if there's such a prize.

The biggest genuine star name of the whole festival, though, is Sinead O'Connor, who has just released her trad and reggae influenced album 'Theology', her first collection of new material  since 2002's 'Sean-Nos Nua'.

Your blogger has a soft spot for Sinead ever since hearing her sing 'Peggy Gordon' a capella at a small fundraising concert in Dalkey a few years ago. It was a mindblowing experience - she has a voice made for traditional Irish ballads.

Here's the great lady singing a live trad-rasta version of  'Óró, sé do bheatha 'bhaile':
