The duet comes more than 75 years after the song was first released. Jenkins' new vocals were recorded and added to the original song, reported Daily Mirror.
The new recording will be released to commemorate the 70th anniversary of the D-Day Landings.
It will also be performed at the 'D-Day 70 Years On' concert at the Royal Albert Hall on June 6.
"It is wonderful that this particular song became the one people most associated with the war era. It makes me proud and honoured to know that 'We'll Meet Again' is still so popular over seven decades after it was first recorded," Lynn said of the record.
