SHINee's Jonghyun and Girls' Generation's Taeyeon performed "Lonely" on the May 13 installment of 'Yoo Hee Yeol's Sketchbook'.

Jonghyun recently dropped his 2nd compilation album 'The Collection: Story Op. 2' and he recruited Taeyeon for the title track. These two are such talented singers so their performance on 'Sketchbook' was so beautiful.
