The name is Ron Kavana, as John also said. There's a great cover version doen by John Wright band from which I got the words (the sweating over a hot tape method) which differ somewhat from those given by Ivan in the second and third verses, as follows:

You fairweather friends,
Where are you now, I need you,
Gone like the autumn wind
On cold December mornings,
When hard times come around,
Like cold and stormy weather
There's only you and I, my love,
To shelter one another.

Now there's a time to fly,
And there's a time for leaving
As the sun melts the snow
On warm, bright April mornings,
our fight has run it's course,
And now's the time for healing,
So let us both embrace
Sweet reconciliation.

The chorus ( if you want to be really pedantic) is Tooralooralie (as in lie down)
Tooralooraladdie
Tooralooralie
Tooralooralay (as in lay an egg!!)
