THE capital was full of musical talent today for Arthur's Day celebrations in Dublin.
More than 80 artists are performing tonight across the country and some famous faces made an appearance as they checked into the luxury Morrison hotel.
Each star will do a high-profile gig in a prominent venue followed by a surprise performance at an unannounced pub.
Not looking like he was short of a dollar or two, singer Aloe Blacc turned up looking dapper in a smart suit and trilby. Earlier in the summer the singer said he "was thrilled" to be invited to perform for the event.
Meanwhile, the retro-loving Scissor Sisters will also be raising a glass to the Irish Godfather of Good Times when they take to the stage at the Olympia in Dublin.
YouTube sensation Ed Sheeran was also among the stars spotted yesterday.
Girl group The Saturdays will perform at the Hop Bar at St James's Gate Brewery in Dublin before their secret gig.
As well as all ticket proceeds going to the Arthur Guinness Fund, which helps social entrepreneurs, fans with smart phones can 'check in' via Facebook while in the pub. For every 'check in', Guinness will donate €5, up to a maximum of €500,000.
