Notably, he also hosted the BBC's television coverage of the Apollo moon landings and the 1964, 1966 and 1970 UK general elections. He was awarded the CBE in 1969.

Michelmore was a RAF squadron leader during World War II, and began his broadcasting career on British Forces Network radio. After the war, he worked for BBC radio and television on a freelance basis; initially as a sports commentator, then as a news reporter and as a producer of children's programmes.

On 4 March 1950, he married his British Forces Network colleague Jean Metcalfe; they went on to have two children.

From 1955 to 1957 Michelmore presented the BBC TV programme Highlight, a current affairs show with a reputation for hard-hitting interviews. On 18 February 1957 he was made anchorman of BBC TV's new topical magazine show Tonight, which was broadcast on weekday evenings at 6.05pm. Tonight ran for 8 years and at its peak attracted an audience of 8 million viewers. In 1958 Michelmore was awarded the accolade of Television Personality of the Year by the Guild of Television Producers.

When Tonight finished its run in 1965, Michelmore hosted a BBC One series called 24 Hours, which ran until 1968. In 1967 he presented Our World , an ambitious worldwide TV broadcast featuring The Beatles. At this point he left full-time work in television and headed EMIs nascent video division. He was a regular presenter on BBC One's Holiday programme from 1969 to 1986, and has presented numerous other shows for BBC TV, ITV, and BBC Radio.
