Fintan was  born in County Louth, Ireland.  He is considered by many as a master of the five row button accordion. Performing in Germany, England, Ireland, Scotland, Italy, the United States and many others.

Fintan has now made his home in US.

Here's an excerpt from a review of one of Fintan's concerts at the Leyland Accordion Club, Leyland, Lancaster, England

"... It was then back to instrumental tunes with a few tangos in the form of La Paloma, Don't Cry for Me Argentina and Jealousy. The speed then increased considerably when Fintan switched to playing a selection of Irish Jigs on his Fratelli Crosio button accordion. It was then time for some French tunes starting with Reproach and then Bourrasque...It was only at that point that Fintan noticed that he had not opened the bottom strap on his accordion despite the fact that we heard lots of reeds in his playing...obviously an accordion with good compression"

Fintan Stanley is a wizard of the continental accordion, considered by many connoisseurs to be among the best in Europe if not the world. The renowned Dermot O'Brien will tell you that Stanley is without doubt the best in Ireland.

Fintan will be remembered in these parts for his membership of the famous Gallowglass Céilí Band with whom he played as a youth. Later he did a spell with Dermot O'Brien's famous Clubmen, followed by a number of years fronting his own band with country singer Maisie McDaniels.
