Was this the single version of CSA?

Was this the actual single version of Come Sail Away?

I know that when the song went to pop radio that at almost 6 minutes, it was too long to be a single and they shortened it. According to this, it appears that they took out the entire "Odyssey" section. I am assuming that this was the way it appeared on pop radio in 1978?
I also have seen where the time on the Blue Collar Man single is like 3:35 when the song on the album is well over 4 minutes. What did they cut out on that?
BTW, it is still weird to see Dennis with a beard....
