B1A4's Sandeul prepared a cover of folk singer Sunflower's Lee Joo Ho and their hit song�"In Your Arms" for the April 6th episode of 'Immortal Song 2'.

Before performing, Sandeul expressed, "It's a new challenge. I'm really nervous to stand on stage without my members." Despite his nervousness, the B1A4 member put on a solid, careful performance.

Though the audience loved the combination of Sandeul's soft vocals and the orchestral music, 4men took the final win.
