They put rhythm in the rock

   HOLLYWOOD -- (AP) -- Found: Two guys responsible for many of the raucous rhythms coming out of juke boxes these days.  They are Jerry Leiber and Mike Stoller, both 23, and they can't be arrested for that.
   Though some older folks think it's a crime, the boys can do no wrong in the eyes of the youngsters.  Their rock 'n' rollers have helped propel Elvis Presley and others to a national craze.
   HOUN' DOG . . . Black Denim Trousers and Motorcycle Boots . . . Love Me . . .  these are a few of their hits.  There are more to come.
   Leiber and Stoller contributed tunes to Presley's film,  Loving You.  Now they've got four ditties in the wiggly one's latest film, Jailhouse Rock.
   The Presley songs from the flickers are guaranteed to sell at least a million records and can go from three to five.  Houn' Dog sold five.  Love Me totalled 2,5000,000 and it was never put out as a single record!  It was included as the lead song in an album.
   JERRY IS red-haired, nervous, single, writes the words.  Mike has a high forehead, seems more calm, is married, writes the music and plays piano well enough to land a role as an ivory-tickler in Jailhouse Rock.
   How did they meet?
   "I was going to Fair Fax High in Los Angeles and writing some songs" Jerry recalled.  "I was working with a drummer who put the notes down for me.  He was kind of a slow worker, so he told me about a guy he knew at City College who could write music faster.  He gave me the guy's address and I went and knocked on his door."
   THEIR MEETING may not have been as momentous as that of Gilbert and Sullivan, but it proved just as happy a blend of talents.
   "We worked well together.:  Mike reported.  "We'd sit around, me at the piano knocking out some riffs and Jerry pacing up and down to sing out phrases.  We'd improvise the song as we went along."
   First they invaded the blues field, and when that moved into the general market as rhythm and blues, or rock 'n' roll, the boys were ready to go, go go.  Their big break came when Elvis heard a combo sing Houn' Dog in Las Vegas.  That was it, brother.

   Their secret of success? "Maybe it was because we were still young enough to know what young kids like."
