Insert shell output into vim with many quotes

I have troubles consolidating this shell command:

uuidgen | tr -d '\n' | awk '{printf("\"%s\"", $0);}'

into Vimscript like this:

:command UUID execute "normal! \"=system('...')\<CR>p"

My current attempt is:

:command UUID execute "normal! \"=system('uuidgen | tr -d \'\n\' | awk \'{printf(\"\"%s\"\", $0);}\'')\<CR>p"

Which returns Unknown mark when I run the command. I assume I ended up in escaping hell and don't know how to recover.

escaping hell... ;-]

escape('uuidgen | tr -d ''\n'' | awk ''{printf("\"%s\"", $0);}'')','\\/.*$^~[]')

Note double single quotes in first part. Second part is universal snippet for escaping.

escape('string','\\/.*$^~[]')

From here it should by easy

I feel like this can be done simpler with systemlist()

command! UUID put='\"'.systemlist('uuidgen')[0].'\"'
nnoremap <key> "='"'.systemlist('uuidgen')[0].'"'<cr>p
inoremap <key> <c-r>='"'.systemlist('uuidgen')[0].'"'<cr>

If you didn't mind ' then you can use the string() function which would be even easier.

For more help see:

:h systemlist()
:h string()
