Ross Ryan was best known or remembered for this one:

I AM PEGASUS
(Ross Ryan)

I am Pegasus, my name means horse
And I can fly high with you
But I've changed my course
I am Michael, I am Jeffery and John
And I don't want to leave you
Unless you want me gone

I am Genesis, I have no fear
I make my plans to land for
I plan to stay here
I am Simon, I am Demetrius and John
And I don't want to leave you
Unless you want me gone

I am flying, but let me down
Oh I don't need the things
That once kept you around
It's not too late
To know who I am
I am Sagittarius

Instrumental break

I am flyin' but let me down
Oh I don't need the things
That once kept you around
It's not too late
Do you know who I am

I am Pegasus, my name means horse
And I can fly high with you now
But I've changed my course
I am Michael, I am Jeffery and John
And I don't have to leave you

I am Pegasus, my name means horse
And I can fly high with you now
But I've changed my course
I am Michael, I am Jeffery
I am Demetrius and John
And I don't have to leave you
Unless you want me gone
