Lost My Train of Thought

The conversation's flowing, everyone is hanging off my words
Story's full of interest, the protagonist is undeterred
Building up to something, certain there's a satisfying end
Almost the finish line, and then, and then...

A vacant moment, all too soon, I find myself back in the room

I've lost my train of thought
I'm sure my point was valid, there's no doubt
Can't even remember
Was what it we were talking about
Where did it go?
The information needed isn't there
Wouldn't you know?
This is no use at all
We're left with a shortfall
I simply can't recall

My friend has got the floor, his insight is concise and critical
Comment with authority, but don't get too political
Subject was on Channel 4, I'm confident to interject
Time for my killer punch, and yet, and yet...

A vacant moment, all too soon, I find myself back in the room

I've lost my train of thought
I'm sure my point was valid, there's no doubt
Can't even remember
Was what it we were talking about
Where did it go?
The information needed isn't there
Wouldn't you know?
This is no use at all
We're left with a shortfall
I simply can't recall

In a fog, I've drawn a blank
The ship I'm sailing in on sank
Circumnavigating with no map
I'm wading through deep undergrowth
Less responsive than a sloth
In some netherworld with no way back
Got no sense of clarity
Only thing that's clear is...

I've lost my train of thought
I'm sure my point was valid, there's no doubt
Can't even remember
Was what it we were talking about
Where did it go?
The information needed isn't there
Wouldn't you know?
This is no use at all
We're left with a shortfall
I simply can't recall

I've lost my train of thought
