Hi a quick query. Can anybody tell me who a company were called 'Thomsun', who apparently produced unauthorised cassettes way back in the 1990's?   I found a cassette from way back called 'The Very Best of Daniel o' Donnell' Originals - which is not the authorised album version of the same title by Ritz/Rosette (different songs altogether).   This unauthorised compilation included my late father's song 'My Bonnie Maureen'.

I only found this a few weeks back in a charity shop. However, I am quite curious as to which country this was produced in - and pleased that they thought the song was worth including a a best of track, considering at this time of writing nobody has re-hashed the song in any other O'Donnell compilation.
I would guess that the compilation must have come out way back in the early 1990's. Numerous pop acts had their releases out by Thomsun back then. It looks like they ran cassette factories of some sort.   I would just like some information for posterity.
