Hi Liland the pone you are probablt thinking of is one I learned at school but not from the teachers

Hark the herald angels sing
Beechams pills are just the thing
Move ye gently meek and mild
Two for an adult one for a child
Regular administration
just the thing for constipation
How can man to are aspire
When his soul is not on fire
How can man to atr aspire
when his hole is not on fire
