Hi charles,
You have really picked one of the most famous songs.
The title is:
"If You Could Read My Mind".
and it is on the albums:
"If You Could Read My Mind" (obvious, heh?)
"Gord's Gold" and
"Songbook Collection".
The complete line you are referring to is:
"What a tale your thoughts could tell
Just like a paperback novel
The kind that drugstores sell"
You can find the complete lyrics here:
