In the second and third chorus the second time is sung differently.

Instead this:
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan
(kauntodaun)
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan

Need this:
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan
(uraura ryaryaryarya totechitetonshan)
hii fuu mii yoo itsu muu janjan
(kauntodaun)
(uraura ryaryaryarya totechitetonshan)
muu itsu yoo mii fuu hii janjan
(uraura ryaryaryarya totechitetonshan)
muu itsu yoo mii fuu hii janjan
