Yeah I don't hear Stan Mark here on any solos at all. Mark was a fine lead player but no scream player. He would tell you that himself. In his "masterclass" interview he describes all the other trumpets as "better high note guys".
The solo was The BOSS all the way but brilliantly supported by a superb band and especially and awesome trumpet section led by the immaculate Stan ‘the man’ Mark
Actually I think the trumpet solos on this cut were done by Stan Mark, who played lead trumpet with the MF band for something ike 14 years. Check the liner notes, but I believe this is Stan not Maynard. but i do agree great sound and Maynard brought it to us for years and it is a shame we have lost it.
