Firstly, I know there are several questions on here about apostrophe-s, as well as capitalising mid-sentence, but I think this is quite unique.
I have the below sentence:
"With an expanding fanbase, collaborations with several artists and support from the likes of the Roots drummer Questlove, she is on her way to success."
Now, "The Roots" is a band i.e. a noun so shouldn't "the" be capitalised? When I looked at a similar sentence in the Guardian, they seem to not capitalise:
The afro comb has long been associated with the 1970s, the accessory of a hairstyle that represented counter culture and civil rights during an important era for both. These days it makes a regular appearance on mainstream TV in America – the Roots drummer Questlove is fond of wearing one while performing as part of the house band on Late Night with Jimmy Fallon.
Second of all, since "the drummer" belongs to the band, does there need to be an apostrophe-s? Many publications seem to think so, such as the below from NME Magazine:
The Roots' drummer Questlove has apologised for an Instagram post which caused controversy and offended...
Lastly, if the above case is correct, shouldn't it be: "The Roots' drummer, Questlove, has..." with commas around his name, as in the following example:
The singer showed off his skills during an appearance on ‘The Tonight Show,’ and even took on The Roots’ drummer, Questlove, in an epic battle.
Similar occurrences would occur if talking about a band like "The Beatles", for instance.
I was tempted to just follow conventions of the Guardian, but there are a low of conflicting uses so I'm not sure. I suppose a solution could be to just omit "the" and say "...support from the likes of Roots drummer Questlove", but "the" is part of the actual title of the band and I would like to know for future reference too.
Your expertise is greatly appreciated!
