While recording for the upcoming November 17 broadcast of JTBC's 'Abnormal Summit',Kyuhyun and Eunhyuk were revealed to have made guest appearances and discussed their fellow Super Junior members.  

Eunhyuk stated, "I feel a bigger generation gap with the people in my group than the junior singers."

Kyuhyun added, "There's only a four year difference between me and Heechul, but our tastes in music are extremely different.  Even when it comes to old singers, I like YADA, but Heechul likes K2," referring to veteran Korean singers.

MC Jun Hyun Moo put in, "But honestly, isn't YADA a very old singer?  I was surprised because Kyuhyun named YADA."

Stay tuned for the full episode of 'Abnormal Summit'.
