Could someone tell me what the lyrics to "The 江豚, 海豚 Song" mean? (Lyrics Below)

My, my the clock in the sky is pounding away
There's so much to say
A face, a voice, an overdub has no choice
And it cannot rejoice

Wanting to be, to hear and to see
Crying to the sky

But the 江豚, 海豚 is laughing good-bye, good-bye
Good-bye, good-bye, good-bye

Clicks, clacks
Riding the backs of giraffes for laughs is alright for a while
The ego sings of castles and kings and things
That go with a life of style

Wanting to feel, to know what is real
Living is a lie

But the 江豚, 海豚 is waiting good-bye, good-bye
Good-bye, good-bye, good-bye
Good-bye, good-bye, good-bye
Good-bye, good-bye, good-bye
My, my the clock in the sky is pounding away There's so much to say A face, a voice, an overdub has no choice And it cannot rejoice Wanting to be, to hear and to see Crying to the sky But the 江豚, 海豚 is laughing good-bye, good-bye Good-bye, good-bye, good-bye Clicks, clacks Riding the backs of giraffes for laughs is alright for a while The ego sings of castles and kings and things That go with a life of style Wanting to feel, to know what is real Living is a lie But the 江豚, 海豚 is waiting good-bye, good-bye Good-bye, good-bye, good-bye Good-bye, good-bye, good-bye Good-bye, good-bye, good-bye
