We're back to the 70s Hiromi Iwasaki（岩崎宏美）which means her bright, brassy and disco-sprinkled aidoru tunes. "Omoide no Ki no Shita de" (Under The Tree of Memories) was created by veteran lyricist Yu Aku（阿久悠）and veteran composer Kyohei Tsutsumi（筒美京平）as Iwasaki's 8th single in January 1977, and has the singer trilling triumphantly about that special day of declaring one's love under that tree. Although it was first sold just a few weeks after New Year's, it sounds a whole lot more summery.
Whenever I listened to those 70s Oricon-friendly pop songs, I would usually hear the battery of strings and/or that sharp trumpet, but for "Omoide no Ki no Shita de", it was the first time to hear a French horn start things off which is how I remember this Iwasaki entry. The horn popped up one more time, I guess, in the song but it certainly left an impression. It peaked at No. 7 and ended the year as the 54th-ranked single. It was also a track on her 4th album, "With Best Friends" that came out in May 1977 and also went as high as No. 7 on the album charts.
