After the huge public response to last year's worldwide celebration of the 250th anniversary of the founding of the Guinness brewery and the legacy of its founder Arthur Guinness, Arthur's Day returns tomorrow with one heck of a line up.

Snow Patrol, Manic Street Preachers, Brandon Flowers, Westlife, Biffy Clyro, Plan B, David Gray and Imelda May are among the many, many top class acts performing in venues throughout Dublin, Cork and Galway tomorrow. You can find the full line up here on our Festivals page. Some if not all of these major players will be making an appearance on the Red Carpet at St. James' Gate Brewery tomorrow afternoon. Along with staffer John Balfe, I'll be making my way down to the brewery to have a quick word with some of them as well as tweeting live from the event.

Meanwhile, John will be having a more in-depth conversation with The Script about their part in proceedings tomorrow morning, while I'll be catching up with rap's next big thing Tinie Tempah on Friday. In the meantime though, you can hear what Paolo Nutini had to say about Arthur's Day when I caught up with him earlier this afternoon here.

And on Friday morning, we'll also have a round-up of some of the best live music on the night. So whatever you do this Thursday September 23rd make sure to catch some music and raise a pint of the black stuff to Arthur Guinness at 17.59.

To Llamas!
