He is Going
Tchaikovsky Research
He is Going (Он идёт) was a humorous song supposedly written by Tchaikovsky to words by Aleksey Apukhtin during the first half of the 1860s (ČW 434) [1].
According to Fyodor Malinin's memoirs, one day Tchaikovsky and Aleksey Apukhtin were walking along the Nevsky Prospekt in Saint Petersburg when a tall and stately guardsman outstripped them. Then and there Apukhtin fashioned a short poem He is Going and Tchaikovsky set it to music [2].
There is no other evidence to corroborate this account, and neither the score nor the poem has been traced.
