70's Pop in Sonnet Form. Can you Guess the Song?

Doth you prefer sweet pungent fruity drinks
And being captured ‘en the heavenly rain
If thou hast at least half a brain to thinks
And desires embracing in sands of Spain

Then I’m the lover thou hath desired
Inscribe a letter and send it post haste
Then I did not consider my ladies heart
For this was a fear that I did not face

Our love had faded; simply gone away
And after a night of loneliness
A letter I wrote and sent the next day
Of which I felt no guilt despite my ladies comeliness

To my surprise I happened upon my lady
Who then laughed as I smiled gayly
