In 2010 Mary Waddington came by bus from England to perform at our Denver Day. One of the songs she sang at this performance was her tribute song for John: 'Postcard for John'. She also sang this one, with some John Denver covers at her performance in 2022. The bus was replaced by the train of Eurostar this time.

Mary often sings at events the the English 'Friends of John Denver'.

Sometimes she has an appearance at the BBC.
