Laura Nyro, one of my favorite songwriters from this era, wrote both songs. She originally released an over-produced version of ‘Save The Country’ in 1968 (Columbia Records was pushing for a hit), but recorded a solo version of the song for 1969’s New York Tendaberry album:
The 5th Dimension had a big hit in 1969 with Nyro’s ‘Wedding Bell Blues’. Featuring, in my opinion, the most gorgeous woman in the history of rock ‘n soul, Marilyn McCoo.

An aside apropos nothing: Hillary Clinton came to Cab Calloway for a campaign event shortly after l’affaire Lewinsky. The school’s chorus, apparently without a hint of irony, sang ‘Wedding Bell Blues’. I LOL’d.
