Not sure if Addicteds have watched G-Dragon's SAL making video! The last part of the SAL making video PART 1 has a cut of G-Dragon sitting on stage, staring out into space while humming along to a song! Let paste the photos~and slowly explain it to everybody!

This part!
Look at Jiyong's facial expression, seems to be in a daze, like he's thinking of something. Totally in his own world and humming along to a song affectionately!



And what song was G-Dragon humming to? After repeating it many times and making comparisons, I finally figured out that G-Dragon was humming along to Taeyang's Where U At! The following photo is a capture of some VIPs' comments on Youtube, which support my thinking!

Now, we have the questions, why would G-Dragon sing Where U At for no reason, even singing like he's in deep thought! I think everyone is all thinking of one answer, the only answer. The only person missing during SAL period was Park Bom, so G-Dragon must have been thinking of Park Bom while singing Where U At! Please don't say that he was calling out for a BIGBANG member, this song is meant for girls! Besides, G-Dragon can meet the BIGBANG members any time he wants, they are a group after all, they'll have activites together in the future, plus BIGBANG did make an appearance near the end of SAL, therefore I am very sure that Jiyong was thinking of Bom while humming/singing along to Where U At! ^^

Where U At lyrics:
Taeyang:
I don’t even know your name, girl
But I’m going to get you somehow
Just gotta let me know where u at
Cuz your man’s coming
When our eyes first met
You smiled a familiar smile
As if you know me
Making me stop in my tracks
It was only a fleeting moment
But I remember how I felt at that moment
I am afraid that I won’t see you again
I look back to catch a glimpse of you
You are getting farther and farther away
Day and night, high and low
I am here as always searching for you.
I just wanna know if you feel the same
Where u at, where u at, where u at
Tell me now
And let my love for you begin
Where u at, girl
I just wanna know if you feel the same
Where u at, where u at, where u at
When you call my name someday
I will be there right in front of you
The look on your face seemed to say
You understood how lonely I was
That look makes you so unforgettable
You understand me
Teddy:
Oh then I wake up and
Then I’m out my zone
Blink twice then you’re gone
Taeyang:
Is your life as hard for you as mine is for me
When you feel worn out by this cold, cold world
Please hang in there until you find me
I run and run and run searching for you
You become only farther and farther away
Day and night, high and low
Beyond the blue sky
I shout for you as always
I just wanna know if you feel the same
Where u at, where u at, were u at
Tell me now
And let my love for you begin
Where u at, girl
I just wanna know if you feel the same
Where u at, where u at, where u at
When you call my name someday
I will be there right in front of you
Now let’s go
Let me break this down
You may be listening to this song somewhere
Let me promise you now
You are meant for me so
I’ll be there for you
I just wanna know if you feel the same way
Where u at, where u at, where u at
Tell me now
And let my love for you begin
Where u at, girl
I just wanna know if you feel the same
Where u at, where u at, where u at
When you call my name someday
I will be there right in front of you


This is the SAL making video, Jiyong starts singing Where U At at around 9:00! Initially, you might not be able to hear it, because I couldn't make a judgement despite replaying it many times too. Just pay more attention from 9:14, he sounds just like Baebae!



This is the Where U At M/V! From 0:59 onwards, it's the verse that Jiyong had sung!



The verse that G-Dragon had sung should be this one, aite?
It was only a fleeting moment
But I remember how I felt at that moment
I am afraid that I won’t see you again
I look back to catch a glimpse of you
You are getting farther and farther away
Day and night, high and low
I am here as always searching for you.
