wav'in falg与南非世界杯主题曲
《wavin's flag - k'naan》与《飘扬的旗帜（wavin' flag）南非世界杯主题曲》有什么关系啊，这两个歌词不一样啊。第一个上来就唱when i get older。另一个唱give me ***这段（而前一首根本没有这一段）。下面是这两个歌词：
首先是我更加喜爱的wain'in flag的歌词：
when i get older
i will bestronger
they'll call me ***
just like a wavin flag
when i get older.......
born to a throne
stronger than rome
but violent prone
poor people zone
but its my home
all i have known
where i got grown
streets we would roam
out of the darkness
i came the farthest
among the hardest survive
learn form these streets
it can be bleak
accept no defeet
surrender retreat
(so we struggling)
fighting to eat
(and we wondering)
when we will be free
so we patiently wait
for that faithful day
its not far away
but for now we say
when i get older.........
so many wars
settling scores
bringing us promises
leaving us poor
i heard them say
love is the way
love is the answer
that's what they say
but look how they treat us
make us believers
we fight there battles
then they deceive us
try to control us
they couldn't hold us
cause we just move forward
like buffalo soldiers
(but we struggling)
fighting to eat
(and we wondering)
when we will be free
so we patiently wait
for that faithfully day
its not far away
but for now we say
when i get older..........
and everybody will be singing it
and you and i will be singing it
and we all will be singing it
wo wah wo ah wo ah
when i get older............
下面是南非非官方主题曲wav'in flag的歌词：
give me ***; give me fire;
give me reason; take me higher
see the champions take the field now.unify us; make us feel proud
in the streets our heads exaliftin,
as we lose our inhibition.
celebration, it surrounds us, every nation all around us
staying forever young,
singing songs underneath the sun
let's rejoice in the beautiful game.
and together at the end of the day.
we all say
when i get older........
下面的歌词就是上面两段的重复...
我就想知道他们是什么关系啊，都是一个人唱的，为什么两个不一样的，只不过第一首感觉更好听，但是批判性太强，是不是本来写的第一首，然后官方觉得太激烈，所以把措辞改的缓和了些形成了第二首非官方的南非世界杯主题曲。
令注：官方南非世界杯主题曲《waka waka》（相当于《我和你》），非官方世界杯主题曲《wan'in flag》（相当于《北京欢迎你》）
