Elton John admitted last month that he recorded a duet with Morrison for the record, a mash-up of his iconic songs 'Mona Lisas And Madhatters' and 'Rocket Man'. However, Morrison claims there are two further collaborations that have yet to be revealed.
According to Yahoo News, after recording the duets Morrison declared: "[My] dreams have all come true".
The former Broadway star described the album's sound as "very eclectic", saying that he tried to draw on singers who inspired him as a child, such as Dean Martin.
The album's first single is expected to be released in three weeks' time, following which the album itself will be released in May.
