'I'm here all by myself ... No guitar, no piano, no nothing!' Trump says Hillary needs Beyoncé to pack 'em in as he draws 11,000 in Pennsylvania

Donald Trump attracted an estimated 11,000 people to a Pennsylvania hockey arena Friday night, and quickly boasted that unlike Hillary Clinton he didn't have to share top-billing with a singer to lure in the crowds.

'We are gonna win Pennsylvania big!' he said as he surveyed the nearly packed house in the famed chocolate town of Hershey. 'Look at this. I hear we set a new record for this building!'

'And by the way, I didn't have to bring J-Lo or Jay-Z – the only way she gets anybody,' the Republican presidential nominee boasted. 'I'm here all by myself. Just me. No guitar, no piano, no nothing.'

'But you know what we do have? And it's all of us. It's all the same. We have great ideas and great vision for our country.'

At about the same time, Hillary Clinton was set to share the stage with Jay Z and Beyoncé in Cleveland, Ohio – a heavily Democratic hotbed that she desperately needs to mobilize if she is to have any chance of winning the Buckeye State on Tuesday.

On Sunday she'll go back to northeastern Ohio for a get-out-the-vote rally with Cleveland Cavaliers star LeBron James.

Trump's campaign manager Kellyanne Conway, a noted pollster, made a first-time appearance as a warm-up speaker – highly unusual for someone in her role – and said the ordinarily Clinton-friendly Pennsylvania was 'a dead heat'.

Then she looked around her at the sea of faces and campaign signs.

'When I look at this packed house, I'm reminded of a joke we have on the campaign that when Donald Trump visits a venue, he attracts the largest crowd in history for someone who doesn't play an instrument and doesn't play a sport,' she said.

Clinton's crowds do tend to balloon when she isn't the only act.

Friday's Beyoncé and Jay Z event will draw 13,610, which is the full capacity of Cleveland State University's Wolstein Center.

Earlier in the day she attracted just 2,539 people for a speech in the concourse under Heinz Field in Pittsburgh.

In between those stops came a joint appearance with 'Shark Tank' personality Mark Cuban in Detroit, which 4,137 attended.

On Thursday night Trump drew a crowd of 17,500 to tiny Selma, North Carolina. An hour's drive away in the city of Raleigh, Clinton needed the help of Pharrell Williams to pull in 4,180.

The pattern repeats itself: Wednesday in Tempe, Arizona, 15,000 people showed up to see Clinton on stage with music and fashion icon DJ Cassidy.

A day later she spoke to 1,880 in Winterville, North Carolina.

Clinton has also co-opted enormous concert events featuring Adele and Jennifer Lopez, making brief appearances at voter-magnets that her campaign didn't organize.
