David Palmer - who did orchestral arrangements for Jethro Tull before being made a fully-fledged member of the band in the late 70s - did several of these orchestral arrangements of progressive rock albums in the mid-80s through mid-90s. Tull, Genesis, Floyd, Yes, and Queen were all given the Palmer treatment between 1986 and 1996. The Tull and Yes versions (at least) even include actual members of the band. To be honest, none of them are particularly good. Palmer was trying to recreate a period when he felt classical music and rock were moving closer together at the peak of prog; a nice enough idea, but he regrettably ended up doing a disservice to both.
