If you want specific highlights - Sorry, Sheís So Fine, Wedding ring, Iíll make you happy, Good times are all great
Yes Easybeats stack well with Simon and Garfunkel in terms of great singles even if Simon and Garfunkel are a better artist overall as they actually written more than one good album.
However a more fair comparison is with the British Invasion group
Easybeats have a better singles output then let say Monkees, hollies, Dave Clark five. I would put them marginally ahead of Animals
Although zombies are much better (although I think they are tier one in terms of quality singles)
I was being facetious regarding no impact outside US. Although I do think that British Invasion covers of the blues, 50ís rock, soul to be more enjoyable than the original
