FUNx4 is a song by Eiichi Ohtaki from his 1981 album A Long Vacation. The song is at No.9 on B Side of the album.

Note: A Long Vacation is one of my favorite Japanese Albums. I wanted to translate this for a long time but never really got around it until mid of last month when I finally decided to buckle up and start translating it right from the first song.

手に入れてしまったよ
お目当てのあの娘を
I got the girl of my dreams
コテージをさまよい出て
Got out of the cottage to wander about
星の降る Starry Starry Night

今宵もギター抱いて
眠るつもりだったのに
I had planned to sleep with my guitar
In my arms today as well
「散歩しない?」って呼び出されて
“Wanna go for a walk?” I was asked
暗がりで Kissin' In The Dark
In the darkness and Kissin’ In The Dark
(とんとんとん) 拍子さ
Tap-tap-tap goes the beat (the sound is actually ton-ton-ton but I have translated it to tap-tap-tap)

Note: dark and dark kind of seems redundant but sounds much better in the Japanese version because they sound like two different words

さあ ポーカーなら Aのフォー・カード
今つきまくった ぼくに賭けなよ

Don’t gamble with me who just struck luck
