The buildings themselves grew - no big deal. The minister (now senior minister) is still there - which is a very big deal for us. (Otherwise I probably wouldnt have gone back there to begin with.) But the service itself is different - the biggest noticable difference being the "contemporarization" of traditional hymns and the large amount of contemporary (modern) Christian music as compared to our younger days.
My wife and I enjoy the "traditional" aspects of the old service as we believe that helped bond the generations together in our former services.
But our choirmaster says (and I really do agree) that we have to throw the old hippies an occasional bone, and the hymns are the least offensive place to do it. Our motets and anthems are 100% straight up traditional - even when modern in date they are traditional in form - and we do lots of Gregorian chant and we chant the Ordinary of the Mass in Latin on First Sundays.
We will gradually phase out the tacky hymns and hope the hippies can get used to it.
Catholic music is a problem in many parishes, and has been since the wholesale jettisoning of tradition after VCII. But the good stuff is making a comeback. As I noted above, you have to shop around a little.
