RADIO

You’ll probably be hearing them quite enough during the 180-hour telecast of the Seoul Olympics on NBC, but--just in case you haven’t--songs from the official sound track of the Olympics are going to be aired often on the radio, too. Five songs from the 11-tune Arista album, “The 1988 Summer Olympics Album,” have already hit the singles sales and airplay charts with “bullets” (denoting fast movement up, or down, these charts). Included among the Hot Five are John Williams’ symphonic theme (“Olympic Spirit”), Whitney Houston’s “One Moment in Time” and the Bunburys’ “Fight.” (The Bunburys are that alias-laden band of British rock superstars a.k.a. George Harrison and Eric Clapton.)
