Franz ___, Austrian composer who was buried next to Beethoven, at whose funeral he had been a torchbearer (8)
I believe the answer is:
schubert
(Other definitions for schubert that I've seen before include "barman" , "Franz --, his Unfinished symphony is famous" , "Franz --, Viennese composer" , "Franz -, Austrian composer (Trout Quintet, etc)" , "Composer of song-cycle Winterreise" .)
