Track three is "Kekkon Shiyoyo", originally by Takuryo Yoshida. Here you will find a live performance. MFAGG usually incorporate some traditional punk sound into their covers. For this song, they use the intro of Social Distortion's Story Of My Life, which somewhat resembles the Japanese original, and works very well.
Track four is "C-C-C", originally by The Tigers. This time, the intro is borrowed from Agent Orange's Bloodstains.
Track five is "22 Sai No Wakare", originally by 70's band, Kaze.
In my opinion, music from Me First and the Gimme Gimmes only works when you can compare their renditions to the originals. It took a bit of searching to find all the songs, but after doing so the EP is even more enjoyable to listen to. I look forward to their next foreign-language release, as I understand they are planning songs from some other countries as well. Enjoy!
