天蒙：一路上心中事不敢倾吐，千万言尽托付六根弦索
                                      尼娜：一路上我也是想说未说，归来后悔又恼牵肠挂肚
                                      天蒙：我弦上弹不尽毋忘曲
                                      尼娜：我怀中也藏着知心歌，这支歌曾是嫩芽难出土，种子唯在梦里播
                                      天蒙：一朝雨露润心田，心歌唱绽花万朵
                                      尼娜：这支歌曾如天时难捉摸，像风像霞像云雾
                                      天蒙：如今是歌中融进心两颗，它定会似胶似漆似甘露
                                      尼娜：这支歌旁人听不懂
                                      天蒙：唯有你我两心合
                                      尼娜：毋忘曲配上知心歌，甜枝甜穗结甜果。）
