The organiser of a Sheffield music festival has said he would love to put on "the party we all deserve", if restrictions ease in time for summer.
In North Yorkshire, Deer Shed festival has also said it will take place.
The government has said limits on social contact in England could be lifted by 21 June.
That would mean many outdoor events could go ahead, including Camp Bestival and Creamfields, which plan to stage their 2021 editions.
Some festival organisers have echoed Conservative MP Julian Knight's calls for the government to offer cancellation insurance.
Mr Knight, chair of the Digital, Culture, Media and Sport select committee, has asked Chancellor Rishi Sunak to announce extra support for festivals in Wednesday's budget.
Mr Cleasby said the measure "would be a massive step in the right direction, because getting cancellation insurance is virtually impossible."
Tramlines is scheduled to take place from 23 to 25 July at Hillsborough Park.
