Not sure if Nigel Olson is who you are talking about but this is part of the Blabbermouth article regarding this subject:
In a 2009 interview with Music Radar, Sorum spoke in more detail about his drumming approach on "November Rain", explaining, "The track I get the most amount of grief for, from drummers, is 'November Rain'. The reason I did that tom fill so many times is I felt it was a musical part. A lot of drummers were like, 'Why'd you play the same fill so much?!'
"Me and Axl were sitting in the studio late one night, having a couple of drinks and listening to Elton John, a song called 'Don't Let The Sun Go Down On Me'.
"Axl goes, 'Do you hear that?' I'm like, 'Yeah, I love Nigel Olson, man'. He says, 'Do that on the song we're going to record tomorrow!' We'd rehearsed it but I didn't have all the fills and stuff, it was just a groove. In the end of 'November Rain', I get into that whole marching band trip."
