Compounding the pressure during what Harrison himself would refer to as "the naughty period, 1973–74", he was drinking heavily and had returned to his drug-taking ways of the 1960s. Some of Harrison's biographers suggest that this abandoning of the "semi-ascetic" path espoused on his 1973 album "Living in the Material World" was Harrison's reaction to the media's sniping, particularly in Britain, at the pious content of that album, as well as a reflection of Harrison's despondency over the failure of his first marriage. These two issues informed the lyrics to a new Harrison song, "Dark Horse". Friend and confidant Klaus Voormann has described this time as an obvious "step back" on Harrison's spiritual journey, Harrison addressed this behaviour in "Simply Shady" and laid out his feelings on the couple's inevitable split in "So Sad".
