Business graduate seen following beginnings of song and dance (5)
I believe the answer is:
samba
'dance' is the definition.
(Brazilian dance)
'business graduate seen following beginnings of song and' is the wordplay.
'business graduate' becomes 'MBA' (Master of Business Administration degree).
'seen following' means one lot of letters go next to another.
'beginnings of' says to take the initial letters (the beginning letters).
The initial letters of 'song and' is 'sa'.
'mba' after 'sa' is 'SAMBA'.
(Other definitions for samba that I've seen before include "This ambassador's > brisk steps" , "South American dance" , "moves from Brazil" , "Dance, originally from Brazil" , "it was launched in Brazil" .)
