When it comes to songs from the '60s, I notice that for any song, you can take the word 'love' and replace it with the word 'drugs', and it will still make sense.
The “Ruttles” version of that song was “All you need is CASH”
Wow, really changes things when the Beatles' "And I Love Her" is changed to "And I Drug Her"
"Mud" seems to fit, too.
