是Il Divo的Mama
他们属于Popera风格，不是美国人，好像是欧洲不同国家的人。四个人音域不同，组合古典的高中低音一应俱全，和声也不错。
歌词是这样的
Mama thank you for who I am
Thank you for all the things I'm not
Forgive me for the words unsaid
And for the times
I forgot
Mama remember all my life
You showed me love,you sacrificed
Think of those young and early days
How I've changed
Along the way (along the way)
Bridge:
And I know you believed
And I know you had dreams
And I'm sorry it took all this time to see
That I am where I am because of your truth
And I miss you , I miss you
Mama forgive the times you cried
Forgive me for not making right
All of the storms I may have caused
And I've been wrong
Dry your eyes (dry your eyes)
Bridge : BECAUSE I know you BELIEVE
Mama I hope this makes you smile
I hope you're happy with my life
At peace with every choice I made
How I've changed
Along the way (along the way)
Cause I know you believed in all of my dreams
And I owe it all to you ,mama
