Irish dance stepped up to the nth degree with some dancers from Ireland. High degree of musicianship including two violins. Traditional Irish tunes and dance melded with Rock, thus the name "Rockin' Road to Dublin". The rock songs chosen were top hits. Rock vocalists do an extremely good job.
They played the Irish song Butterfly, delicately performed and dance to, with the female troupe using ballet slippers. The sped-up part to follow was not the reel, but rather a rock and reel, guy dancers joining in. In all cases the Irish was preserved, but when they rocked, they rocked. Another rock song as part of a rock medley was Baba O'Reilly (Teenage Wasteland) originally recorded by The Who.
The Scottish drum was used on a show down with the lead male Irish dancers. Then another drum was added. Then another, while adding male dancers. You must decide who wins.
Taken as a whole, one would be hard pressed to see this degree of musicianship and dance in any touring show: Off the charts!
