'His virtuosity, his dreadlocks and his good looks" were captivating, said Jackie Tyrrell, a nurse from Drogheda, of singer Bobby McFerrin at the National Concert Hall, Dublin. Her two friends, Anne McWilliams and Geraldine Hall, agreed.
President Mary McAleese was also at the NCH in a personal capacity to enjoy the concert.
"It's hard to believe that two years have gone by since I was here singing on this stage for you all," said the American singer. "I've been travelling a long, long time, but I'm okay."
"His range, his voice. He's multi-talented," said Leo Blennerhassett, a management consultant who brought his two sons, Daragh (14) and Conor (16), to listen to the magic of McFerrin.
Shay Healy, the creator of The Wiremen musical, was there with singer/songwriter Don Mescall and engineer Philip Begley.
Before he took his leave, McFerrin answered some questions from the stage, such as: what do his strange-sounding lyrics mean?
"I'm just making something up, something that sounds fun. But I think that we all have pockets of memory that we access at particular times. My father's memory and his father's memory sometimes come out. Now that's just a theory," said the winner of 10 Grammy awards.
"He was amazing," said jazz singer Cormac Kenevey, who'll be singing from his debut album, This is Living, in Bewley's Theatre, Dublin, on Thursday, August 18th.
Jazz pianist Cian Boylan and singer and cellist Vyvienne Long, who'll be performing in Whelan's, Dublin, on Wednesday, July 20th, thought the same. Boylan especially loved McFerrin's rendition of the Charlie Chaplin song, Smile (though your heart is aching).
Also at the concert was John Mardirosian, director of Waltons New School of Music, which presented McFerrin as part of its Waltons World Masters series at the NCH. He was there with his sons, Samuel (12) and Eoin (nine), and his wife, Aideen.
"It was so quirky and offbeat. I loved it," concluded Carol Anne Hennessy, from Midleton, Co Cork.
