Hi George
if you are in the Las Americas Los Christianos areas there is allegedly a session at the Claddach one level up from the beach on a Sunday afternoon. From what Ive heard it can sometimes be very good and varied

For Irish trad? the Chieftain underneath the Columbus Aparthotel is good entertainment if Terry Bury is playing. if you are a singer/player he is happy to let you do a few numbers.
The Irish Fiddlern and the Temple bar at San Eugenio are owned by the same Irish couple as the Chieftain and provide similar "irish Pub" entertainment.
Kitty O'Sheas is at the Marina below Sam Eugenio and i believe a reasoably well known irish performer is based thee (Dave Breen?)

If its entertainement with an Irish flavour is wanted McGuinesses bar just off the beach walkway at the north end of the Mediterreanian palace can be recommended music is proveded by Adrian Brooks except for the 16- 18 feb when Phil? a very good keyboard player singer and entertainer will be filling in for Adrian.
Hope you enjoy Teneriffe
I Have missed out on the Dublinner and Fitzparticks at Veronicas and thh Irish Corner at the "Patch" which are very young pop /irish at present
Kenny B
