Predebut B1A4 Sandeul Singing Compilation 

I'd had loved you even as Lee Junghwan even if you were not B1A4. If I knew you in person I'd had falled for LEE JUNGHWAN. I love our Sandeul so much, but I will love him no matter how normal he is. He doesn't need to be the most handsomest. He still will be loved forever.

He looks nerdie cute back then but he is so handsome namja now

Oh my god. The second to last one... 소름 완전 짱 대박 wow this child needs a solo album rn

His voice has always been so rich and lovely

멋진노래 불러줘서 항상 고맙고 언제나 바나들 1순위로 생각해줘서 고마워요 오빠들 언제나 사랑해♥ 보는 내가 마음이 찡해지네 헝헝..

Sandeul's voice is totally awesome since predebut until now! strong voice~ *0*

hes too amazing. I can't take it. Sandeul, Lee Junghwan. You're my role model and your pure awesomeness is just making me cry right now You're really amazing. I can't wait until you show up on immortal song. Love you so much sandeul

I'm crying right now.. God, how can he be this good? his singing skill is no joke! you're a great singer, Sandeul-ah.. you're the best singer :")

He looked so cute and handsome. He sings so well and his personality is so cute I'm in love😭

Wow, I never realised until I heard him singing solo, but his voice is amazing. Of course he works and trains INSANELY hard, but his voice is a gift from God. That or he ate a lot of CDs ;) I want to sing like this too.

I'm always so jealous of his voice. If I could live as someone for one day I would live as Sandeul and sing all day.

サンドゥルは基本バラードが好きなのがよく分かるね😊 歌い方も変わってなくて素敵だわ。 学生の頃から凄く上手くて驚くΣ(°Д°)👏😊👍👍✨

5:24 Sandeul you are so amazing!!!

Zaaaamn his voice is incredible!

Banas' Deullie is one of the greatest rookie singers!! :D This is what you call TRUE talent.

Oh goddd. His voice is soo good. He should get an award!

I'm actually scared that he would leave and debut solo. I know that he would be really successful but I think B1A4 would have that empty hole that is Sandeul's childishness, wonderful voice, his delighting presence, the light and happiness that radiates from him and simply him. He's a ball of energy that's like B1A4's sunshine.

He look older in the old hairstyle.. but still, i love him no matter how he look back then and now

Sandeul has a greatest voice and I just surprise with his diet program wow~ he's too difference DDDDx

He looks so different!...

음색이 참 좋다. 성량도 풍부하고 ㅎ

Oh my~ such a voice on this guy. I look up to you always Lee Junghwan!

Thank God he get to show his talent through B1A4. 3

Sandeul! You're my idol! Fo real. I wish I can sing like you! :(

bu then b1a4 wouldnt have their little duck :c

May I ask what years these were filmed during? I don't need all the individual clips, just a range! He looks pretty young in these, but his voice was amazing already.

@tIgGeRnPoOh25 but he would be lonelier and he wouldnt have so much fun with his fellow members now :D

5:20!

What?!! He used to wear glasses?

What are the names of the songs 2:02, 4:10? I'm not Korean but I love Korean songs and Sandeul. Please share names of singers and songs in English, if possible youtube links. Thanks.

b1a4 is not the same with out sandeul

3:45 who knows what's the song here ?

He loss weight to debut

OMG I adoree your voicee ♥♥ sandeulliee !! Love u ~
