Another nice Roy Rogers 'tribute' song is 'If I Had A Boat' by Lyle Lovett, for which someone made an irreverent extra verse:
When Trigger died Roy Rogers
Had him stuffed and he put him
In a museum, you can see him there today
Roy must have loved his horse a lot
To do a funny thing like that
So I hope his wife is feeling quite o.k.

It's supposed to be true. - Susanne
