Consider this run from late '65 on thru early '69:
"Look Through Any Window"
"If I Needed Someone"
"I Can't Let Go"
"Bus Stop"
"Stop! Stop! Stop!"
"On a Carousel"
"Pay You Back With Interest"
"Carrie Anne"
"King Midas In Reverse"
"Dear Eloise"
"Jennifer Eccles"
"Do The Best You Can"
"Listen To Me"
"Sorry Suzanne"
The ones in bold are the pinnacle afaic, but c'mon, these are all well-crafted, well-preformed radio-ready nuggets with a distinct musical and lyrical POV. That's doing something!
And the vocals remind me of Everly Brothers brought back across the ocean and reintroduced back to their origins, indirectly.
Besides the amazing vocals, check out the tight but energetic playing on "On a Carousel". Pretty damn in there, eh?
I think The Hollies should be respected for their 1960s work. Like I sad, the 70s/beyond stuff is ok for them that want it, but me, give me this.
