I haven't seen the ad, Angela. Is it the same music as was used in ye olden days? If so, it's from Antonin Dvorak's New World Symphony (Symphony No. 9 in E minor) 2nd movement, Largo. If this is the piece, it can be found on most classical compilations.
My reply from hovis was:
"Thank you for your email regarding the music used in our new Hovis advert. This piece of music was written specifically for our advert and is called 'Gold'. The musician was Charlie Morgan. However, there are no plans to release this music at the moment. "
I hope that this is good enough.
My question though is
what piece of music (probably an intro to an eighties hit) does it remind me of
