There is a comma missing in the sentence. It should be written as follows, "Had I come to know about his difficulties, I would have certainly helped."
The correction would be: "Had I come to know about his difficulties, I would have certainly helped." The comma is needed after "difficulties" to separate the dependent clause.
Mason Proffit released this album in 1971. Good stuff...
I guess this time you're really leavingI heard your suitcase say goodbyeWell as my broken heart lies bleedingYou say true love, it's suicideYou say you've cried a thousand riversAnd now you're swimming for the shoreYou left me drowning in my tearsAnd you won't save me anymoreI pray to God you'll give me one more chance, girlI'll be there for youThese five words I swear to youWhen you breathe I want to be the air for youI'll be there for youI'd live and I'd die for youSteal the sun from the sky for youWords can't say what a love can doI'll be there for youI know you know we're had some good timesNow they have their own hiding placeI can't promise you tomorrowBut I can't buy back yesterdayAnd Baby you know my hands are dirtyBut I wanted to be your valentineI'll be the water when you get thirsty, babyWhen you get drunk, I'll be the wineI'll be there for youThese five words I swear to youWhen you breathe I want to be the air for youI'll be there for youI'd live and I'd die for youSteal the sun from the sky for youWords can't say what a love can doI'll be there for youSoloAnd I wasn't there when you were happyI wasn't there when you were downI didn't mean to miss your birthday, babyI wish I'd seen you blow those candles outI'll be there for youThese five words I swear to youWhen you breathe I want to be the air for youI'll be there for youI'd live and I'd die for youSteal the sun from the sky for youWords can't say what a love can doI'll be there for you
