Sequences

[Left peg]

Any help please with the next one in the sequences
E, A, D, G, B ? something to do with art, literature or entertainment.
G, HC, KK, NL, M ? something to do with sport

Any suggestions gratefully appreciated.

E A D G B followed by E signify the notes that guitar strings should be tuned to (on a six string classical guitar)

Thinking about the sport sequence...

The 2nd list are recent Derby winners. The next initials are SP (Sir Percy).
