NME:
No. 31 (NME Best 100 Songs of The 1960's (2012)). Penned by Jimmy Webb (who also wrote ‘Galveston’), this was another tale of blue-collar blues. Framed by producer Al DeLory’s wistful orchestration, Campbell’s honey-soaked croon perfectly captured the sadness of a long distance telephone lineman.

Pitchfork.com:
Campbell's 1968 hit, penned by Jimmy Webb, helped define his career with its slick production and strong melody. The underlying sadness in his smooth vocals was pure country, but the sweeping strings and sparkling production were a fresh pop addition. --Cory D. Byrom

Richard:
This is an absolutely beautiful track, highly recommended by VS, The NME, etc, and comprehensively defeats any pre- or mis-conceptions about this sort of music. It's country, kind of tame, lilting, soft, but there's something essential about it, a must find. Glen Campbell's voice is genuine and earnest, it's a lovely tune as well, and there's some (almost bizarre) electronic arrangements coupled with the orchestration and violins that accompany throughout. It's not an immediate song, unless you're into Country, but it grabs and grows and gets better and better. From someone that's NOT a fan of this musical genre, this is essential.
