Mitch Winehouse finds it ''difficult'' to listen to his late daughter Amy Winehouse's songs.

The jazz singer has confessed he often gets upset if he plays Amy's albums 'Back to Black' and 'Frank' because he still finds it hard to accept that she is gone.

Speaking at the launch of his new album 'But Beautiful' at the Pizza Express Jazz Club in London on Monday night (08.09.14), he told BANG Showbiz: ''I find it difficult to listen to her albums, it's upsetting. I like listening to the stuff that I discovered like 'When My Eyes' and 'Fool's Gold'. I loved the stuff she did will Jools Holland and Paul Weller, those are great. Vocally she was at her finest.''

Mitch says Amy's influence can be found on his new LP as many of the tracks were chosen by her for inclusion on his debut album 'Rush of Love' - which he recorded with his daughter before her tragic death in July 2011 at the age of 27 - but didn't make the final tracklisting.

He explained: ''When Amy and I did the first album and we chose the songs, a lot of the songs we chose didn't go on that album and are on this new record. We had like 40 songs - actually it was more like 50 songs - picked out. I think the tracks on this album are the better songs.''

All proceeds from sales of the album - which is released on September 29 on Lioness - will go to the Amy Winehouse Foundation (www.amywinehousefoundation.org).
