I was baptized in '73 myself!
Baptismal questions from the May 1, 1973 Watchtower, p. 280:
(1) Have you repented of your sins and turned around, recognizing yourself before Jehovah God as a condemned sinner who needs salvation, and have you acknowledged to him that this salvation proceeds from him, the Father, through his Son Jesus Christ?
(2) On the basis of this faith in God and in his provision for salvation, have you dedicated yourself unreservedly to God to do his will henceforth as he reveals it to you through Jesus Christ and through the Bible under the enlightening power of the holy spirit?
