Once I   a love and it was a  
Soon turned   had a heart of glass
Seemed like the   thing, only to  
Mucho   , love's gone  

Once I had a love and it was  
Soon found out I was   my mind
It seemed like the real thing
But I was so  
Mucho mistrust, love's gone behind

In  
What I find is   and I'm   fine
Love is so confusing there's no   of mind
If I fear I'm losing you it's   no good
You   like you do

Once I had a love and it was a gas
Soon turned out had a heart of glass
Seemed like the real thing, only to find
Mucho mistrust, love's gone behind

Lost  
Adorable   and I cannot  
I'm the one you're   ,
Please don't push me  
We could've made it   , yeah

Yeah, riding high on love's true bluish light

Once I had a love and it was a gas
Soon turned out to be a pain in the ass
Seemed like the real thing only to find
Mucho mistrust, love's gone behind
