I saw the rating of this album which caused me to respond.
I am not a particular fan of CSNY but this is their best album by far. I was too young to buy at those days but discovered them some years later.
Excellent songs that have survived time somehow.
Carry On is a good opening song. Almost cut my hair brings strong memories for me and has humor in it, nice! 4+20 brings tears in my eyes and is top song, country girl also a classic, definitely a 5/5
