A few leftover tracks were saved or re-recorded for future albums like Veedon Fleece, but most would not see release until 1998's compilation of outtakes, The Philosopher's Stone, when nine of the songs would be used.
Biographer Clinton Heylin suggested that "only 'Warm Love' and 'Hard Nose the Highway' could have sat comfortably alongside 'rejects' like 'Madame Joy', 'Bulbs', 'Spare Me a Little', 'Country Fair', 'Contemplation Rose' and 'Drumshanbo Hustle'.
"[7] "Being Green" is the first non-original composition Morrison had included on any album for Warner Bros. so far and was taken from the popular American children's TV show, Sesame Street, which he must have watched with his young daughter, Shana.
"[9] The ending song, "Purple Heather" is the traditional "Wild Mountain Thyme" written by F. McPeake as a variant of Robert Tannahill's "The Braes of Balquhidder", and re-arranged by Morrison.
He cited one dissenting critic Charlie Gillett, who wrote in Let It Rock: "The trouble with Hard Nose the Highway is that although the music is quite often interesting, it doesn't have a convincing emotional basis...Despite the lack of inspiration and of melodic focus, the record is attractive to listen to.
"[15] Robert Christgau rated it only a B− and mostly dismissed it with: "The relaxed rhythms are just lax most of the time, the vocal surprises mild after Saint Dominic's Preview, the lyrics dumbest when they're more than mood pieces, and the song construction offhand except on 'Warm Love'.
"[16] Stephen Holden in his 1973 Rolling Stone review said: "Hard Nose the Highway is psychologically complex, musically somewhat uneven and lyrically excellent.
[19] In the opinion of biographer Erik Hage, "Hard Nose the Highway seems to have suffered a lot of unnecessary criticism—many commentators consider it his worst and most uninspired album—perhaps because it followed such a remarkable run of LPs, and because two truly forward-thinking albums had come before and after it (1972's Saint Dominic's Preview and 1974's Veedon Fleece).
