After the war, he took up his duties again at the Winter Gardens playing both organs installed there as well as deputising for Reginald Dixon at the Tower with fellow organist, Watson Holmes.
On 14 December 1956 a fire almost destroyed the Blackpool Tower Ballroom and during this time, Dixon took up residency at the Empress whilst Finch was demoted to the Winter Gardens Pavilion on the Hammond Organ.
On 19 October 1962 he made what was to be his last broadcast from the organ of the Opera House as on 16 November, he sustained an injury to his left hand which prevented him from playing publicly again.
[4] He composed a few pieces of light music which were never published, but were broadcast by the BBC including "The Blackpool Express" and "Get Goin'".
Finch did, however, notch up a great deal of air time on the radio during his tenure as resident organist at the Winter Gardens.
