Yo!

There are Five here. Neither of them are what you specifically asked for, but, hey, a man can't get enough of Simpson, right?

You can buy (what? BUY???) a book of Simpson Tabs Here - minus 'The Granemore Hare'. Typical!
I'm not sure if These ones are all the same as the ones on the first link; I recognise Delia, anyway.
But there's a link to a whole pile of tabs from loads of different musicians Here, including Simpson.

So far I can't find either of the two you've specifically asked for. But this might do for a start, and I'll delve a bit deeper later on.

Have fun.
