Summon back to city demonstrating ludicrous change (8)
I haven't cracked this one yet — but Times for the Times have:
BATH (city) then CITE (summon) reversed [back]. SOED: bathos – (of rhetoric) ludicrous descent from the elevated to the commonplace.
Mineral of thulium also containing aluminium and copper (6)
I haven't cracked this one yet — but Times for the Times have:
TM (thulium) [containing] AL (aluminium) + CU (copper). Talc is a naturally occurring mineral composed of hydrated magnesium silicate.
Dance one spied regularly around Royal Navy? (8)

Long time after old Papa Haydn's works? (5)
I haven't cracked this one yet — but Times for the Times have:
O (old), P (papa – NATO alphabet), ERA (long time). Joseph Haydn’s operas tend to have been neglected over the years by comparison with much of his other output, but he wrote a couple of dozen. The surface is apt because the affectionate nickname ‘Papa’ was given to Haydn during his time at the court of Esterházy. Please see Wil Ransome’s comment below for an alternative interpretation of the definition.
Having some power to bond with opponent in camp (9)
What's sticky and hard to throw away? (9)
I haven't cracked this one yet — but Times for the Times have:
Cryptic. This might loosely be described as a stick that comes back when thrown away it – unless you’re Charlie Drake. I was going to put a link to the song but decided to spare you .
Botch at least three notes (5)
I haven't cracked this one yet — but Times for the Times have:
MI’S (notes i.e. 2 or more) + DO (note x 1), so at least three notes

Physicist — one going on and on endlessly about hydrogen (4)

I left in changed form, such as Mr Hyde was known to do (10)
I haven't cracked this one yet — but Times for the Times have:
I + L (left) contained by [in] MUTATION (changed form). I can’t remember the gruesome details of Mr H’s deeds but a summary I found on line advises: “His actions are characterized by a lack of empathy and a willingness to inflict pain and suffering on others” so I assume this may have included mutilation.
