How to embed applescript into a shell script for notification center

Question

I have managed to cobble this together:
You can run it in your Terminal, it is harmless, and will output results that will show you a notification from notification center:
I have items on my pasteboard as the results of a script, I want to pbpaste them into the below command, but can't get the syntax right.  I am not objectionable to string concatenation and building or whatever it takes.
osascript -e 'display notification "The url(s) are on your clipboard from my.app" with title "my.app has finished" subtitle "Some Sub title"'
Ideally, I want to put `pbpaste` in the "Some title" section, but I get the literal string. I try creating a variable, and get that literal string.
I tried building the entire string up as one variable, which in the Terminal echo'd out and works, but in Notification Center, I get the actually literal variable.  It's mainly a bash script, so the context witch to AppleScript i being a pain in the rear.
Suggestions? Any master out there that this makes any sense to?

As it stands, and the way you have your notification structured, this is the output from the notification center. I did an echo "From the clipboard" | pbcopy before I ran the following script. It uses a Bash function, osascript HERE document, and shows how to pass variables to the function, and receive them in AppleScript. If you want substring text that is not the result of pbpaste, then you can either make the string inside the AppleScript, or pass the string in as a variable.
To get this output, I used the following Bash/Osascript combination:
#!/bin/bash
#osascript -e 'display notification "The url(s) are on your clipboard from
#my.app" with title "my.app has finished" subtitle "Some Sub title"'
function notification () {
  `osascript <<-AppleScript
        set txt1 to "The URL(s) are on your clipboard from "
        set txt2 to " has finished"
    set appName to "$1" as text
    set subStr to "$2" as text
    set noteStr to txt1 & appName
    set titleStr to appName & txt2
    tell application "System Events"
        display notification noteStr with title titleStr subtitle subStr
        delay 1 -- give notification time to fire
    end tell
    return quit
AppleScript`
appName="foo.app"
#echo $appName
subTitle="$(pbpaste)"
#echo $subTitle
notification "${appName}" "${subTitle}"
exit 0
