Asu e no YELL is my cup of tea than Weekender, but yeah, both a-side songs are good! The PV also. I read from somewhere that HSJ fans were invited to MSta and requested to bring their smart tour towels, so Asu e no YELL will be sung for sure!
The full single is available here.

Through the night is nice upbeat song. And surprisingly, Hey! Say! BEST solo's Suit Days is an adult version/sequel of School Days! (which is previously release on Magic Power single) lol
