Gola Ola is a welsh band and they're the best welsh band on the scene now(radio luxembourg yn cael brec bach). They're album 'Rhwng Oria a munuda' is very very good and in my opinion the best song on the slbu is 'cei mi gei' and the first track which is an intro is very well planned and funny!

If the sites are wrong i'm sorry, but all you have to do is go on google search and type in 'Gola Ola'
