Who sings song that starts on my way back home attributed to Grand funk Railroad?

Could you be thinking of, " I'm getting closer to my home", repeat, repeat? That would be I'm Your Captain/ Closer To Home off of the Capitol multi- platinum record , Closer To Home. On the album, it may be listed as I'm Your Captain, with Closer To Home being the 2nd part of the song,( 9:47 min.).
