Pride (In The Name Of Love)

One man come in the name of love
One man come and go
One man come, he to justify
One man to overthrow

In the name of love
What more in the name of love?
In the name of love
What more in the name of love?

One man caught on a barbed wire fence
One man, he resist
One man washed on an empty beach.
One man betrayed with a kiss

In the name of love
What more in the name of love?
In the name of love
What more in the name of love?

(nobody like you...)

Early morning, April four
Shot rings out in the Memphis sky
Free at last, they took your life
They could not take your pride

In the name of love
What more in the name of love?
In the name of love
What more in the name of love?
In the name of love
What more in the name of love?
