I have a terrible confession to make : I love Irish music,& have a stab at playing it, but---I"ve NEVER been to Ireland !! So I don"t really know what a true Irish session is like. However,I DON"T NEED to go to Ireland,when I can go to the "Herschel Arms" in Slough , which is apparently as close as you can get to the real thing (whatever that may be ) For me ,the landlord is the most Irish person in the known world, as are some of the musicians I have heard there-Paddy Keenan,Tommy O" sullivan, & ,last monday night, Finbar Dwyer, melodeon legend !! The musicians,some Irish,some of Irish descent,some English even,are superb ,the decor (as far as I know ) authentic,the craic amazing. So why not try it ?? Monday nights, 2100 onwards,not advertised,not commercial,lovely people, woderful sounds !! So there !!
