it's my life里面有一句"For Tommy and Gina who never backed down"

it's my life里面有一句"For Tommy and Gina who never backed down" 里面的Tommy and Gina 是指的哪个?
如题

Tom and Gina是Bon Jovi六十年代的老歌Livin' on a Prayer里的夫妻人物,具体的内容是说他们两个人生活很艰难,但是一直坚持相爱,没有被困难打倒.
所以这里说他们“never backed down”就是“从不退缩”的意思.
原歌词：
Once upon a time 　　很久很久以前
Not so long ago 　　不那么久以前
Tommy used to work on the docks 　　汤米原本在码头工作
Union's been on strike 　　但工会罢工
He's down on his luck...it's tough,so tough 　　他只能碰运气...生活艰苦,如此艰苦
Gina works the diner all day 　　吉娜整日在餐厅工作
Working for her man,she brings home her pay 　　为了她的男人而努力,她为爱情赚养家
For love - for love 　　为了爱情
She says:We've got to hold on to what we've got 　　她说：我们应该珍惜所拥有的
'Cause it doesn't make a difference
If we make it or not 　　成功与否并不重要
We've got each other and that's a lot 　　拥有彼此便已足够
For love - we'll give it a shot 　　为了爱-我们会奋力一试
We're half way there 　　我们正在前往成功的途中
Livin' on a prayer 　　活在祈祷中
Take my hand and we'll make it - I swear 　　握紧我的手,我们会成功—我发誓
Livin' on a prayer 　　活在祈祷中
Tommy got his six string in hock 　　汤米拿了吉它去典当
Now he's holding in what he used 　　那曾是他的最爱
To make it talk - so tough,it's tough 　　生活是如此艰苦
Gina dreams of running away 　　吉娜想要逃离这一切
When she cries in the night 　　当她在夜晚啜泣
Tommy whispers:Baby it's okay,someday 　汤米轻声说：亲爱的没关系,有一天我们会成功 We've got to hold on to what we've got 　　我们应该珍惜所拥有的
'Cause it doesn't make a difference 　　因为一切都没有变化
If we make it or not 　　成功与否并不重要
We've got each other and that's a lot 　　拥有彼此便已足够
For love - we'll give it a shot 　　为了爱-我们会奋力一试
We're half way there 　　我们正在前往成功的途中
Livin' on a prayer 　　活在祈祷中
Take my hand and we'll make it - I swear
握紧我的手,我们会成功—我发誓
Livin' on a prayer 　　活在祈祷中
We've got to hold on ready or not 　　我们一定要撑下去 无论愿意与否
You live for the fight when it's all that you've got 　　既然生来注定就得打拼
We're half way there 　　我们正在前往成功的途中
Livin' on a prayer 　　活在祈祷中
Take my hand and we'll make it - I swear 　　握紧我的手,我们会成功—我发誓
Livin' on a prayer 　　活在祈祷中
