Given the address of an old friend in the 1970s, is it possible to trace their current address (eg. By searching electoral rolls or land registry records)?

Of course, best their ssn... depending on their present age (I would check marriage, devorce, death record, real estate/recorded deed, etc, in the city and surrounding (100miles?) area.. peripherally, info that may lead you to him/her would be via remembered parents a/o sibling names, addresses; local newpapers. Another area I am totally ignorant is geneolgy - moron/lds church have records of all mankind..

Good luck & let us/me know how you come out.
