The Pretenders and Seasick Steve are also on the bill
More acts are set to be announced for both days.
Speaking of playing on the same bill as Neil Young, The Pretenders‘ Chrissie Hynde said in a statement: “We would play a garden shed to be on a bill with Neil Young but Hyde Park – summer – with ‘The Loner’? This is what makes a thousand hours on tour buses all worthwhile. This is why people get in bands.”
Tickets for the Neil Young date go on sale this Friday (March 13) at 9am (GMT). The Springsteen-headlined day has already sold out.
