A man in the audience at a Murrells Inlet VFW hall asked McCain about sending "an air mail message to Tehran," The Georgetown (S.C.) Times reported. McCain began his answer by putting new words to the oldie -- made popular by the Beach Boys and the Regents.
"Bomb bomb bomb, bomb bomb Iran," he sang.
"Iran is dedicated to the destruction of Israel," McCain said in a more serious vein. "That alone should concern us, but now they are trying for nuclear capabilities. I totally support (President George W. Bush) when he says we will not allow Iran to destroy Israel."
McCain did not say whether bombing Iran would be necessary or desirable.
He plans a two-day tour next week to announce his candidacy for the Republican presidential nomination in 2008. He made a preliminary announcement several weeks ago on CBS' "Late Show with David Letterman."
Former New York Mayor Rudolph Giuliani is ahead of McCain in most polls.
