勿忘我 Forget me not – David Tao 陶喆

勿忘我 曲:陶喆 詞:周啟兒

謝謝你曾陪我走過的路 今天只剩你一個人走
再好的故事終究要結束 我知道 yeah~
在我心中的你永遠停在那天 倔強地微笑著的側臉
忍住眼淚的你說不出的再見 卻聽見你輕輕地唱著

Yo De Lay Lay Yo 請不要忘了我
Yo De Lay Lay Yo 你不要忘了我 答應我

謝謝你從不計較的付出 那是多麼單純的幸福
遺憾的是幸福不能彌補 最初的錯誤 yeah~
在你心中的我你要怎麼記住 那些不再紀念的日子
你還是揮揮手裝作毫不在乎 卻低著頭輕輕地唱著

Yo De Lay Lay Yo 請不要忘了我
Yo De Lay Lay Yo 你不要忘了我 yeah~

記得那時候 牽著你的手 什麼都沒說 多笨拙 yeah~
如果還能夠 只想對你說 永遠記得我 記得我 I say yeah~

I say Lay Lay Yo 請不要忘了我
I say Lay Lay Yo 請你不要忘了我 請你不要忘了我
Yo De Lay Lay Yo
Yo De Lay Yo 你不要忘了我
Yo De Lay Lay Yo
你不要忘了我 勿忘我
Yo De Lay Lay Lay
